Biological diversity, or biodiversity, is the scientific term for the variety of life on Earth. Because temperature is an important aspect in shaping ecosystem diversity, it is also used in ecosystem classification (e.g., cold winter deserts, versus warm deserts) (Udvardy, 1975). Hu-mans are an integral part of ecosystems. The variation among organisms on Earth is called biological diversity, or biodiversity. What is the MOST likely location of a biodiversity hotspot? Ecosystem diversity is the variety of living organisms present within an ecosystem. During succession, the patterns of energy flow, gross and net productivity, diversity, and mineral cycling change over time. Linear science has set steps to follow and ends at some point. C. there are many specialized niches. For example, a coral reef generally has a very great variety of life within it, a greater ecosystem diversity than say Antarctica, which is covered by a sheet of ice [17]. Biodiversity refers to the variety of living species on Earth, including plants, animals, bacteria, and fungi. populations of the same species may be separated and would no longer be able to mate. Differences between linear and nonlinear scientific methods. 54. E. there are few producers. Species - A group of more or less distinct organisms that are capable of interbreeding with one another in nature to produce fertile offspring but do not interbreed with other organisms. Each species is the repository of an immense amount of genetic information. Figure 7.1: Climate and non-climate stressors interact synergistically on biological diversity, ecosystems, and the services they provide for human well-being. Species diversity looks at how genes vary within a species, while genetic diversity looks at the variety of ecosystems. What is one major motivation for companies to source sustainably grown palm oil? They are less susceptible to extinction than other species. Biodiversity includes diversity within species (genetic diversity), between species (species diversity), and between ecosystems (ecosystem diversity). Ecological diversity is the largest scale of biodiversity, and within each ecosystem, there is a great deal of both species and genetic diversity. The number of unique species increases with isolation. Biodiversity is measured using biodiversity indexes. Ecosystem diversity - The variety of ecosystems found on Earth. An intertidal species of sea star helps to maintain the diversity of the intertidal region by controlling the mussel population. Ecologists will use more than one index to calculate the level of diversity. Start studying Biodiversity Quiz. Usually, the more diverse an ecosystem the healthier it is considered, which means it is more resilient to rapid changes in environment. What is NOT a cause of habitat destruction? Habitat fragmentation can be detrimental to species because ____________. the variety of all living things on Earth. 2 Ecosystems and Their Services EXECUTIVE SUMMARY An ecosystem is a dynamic complex of plant, animal, and microorganism com- munities and the nonliving environment, interacting as a functional unit. Which of the following is NOT an environmental cost of clearing tropical forests? Biodiversity and Ecosystem Stability c. If conditions become unfavorable, both have a better chance of thriving. Greater habitat diversity leads to greater species and genetic diversity. Each species is specialized to a type of ecosystem in a particular place. Biological diversity - The number, variety, and variability of Earth's organisms; consists of three components: genetic diversity, species richness, and ecosystem diversity. many different species, with one population being overrepresented in the ecosystem, Biodiversity at the community level is known as. 1) protect species richness to maintain ecosystem functional diversity and enhance ecosystem function and stability 2) protect keystone species, which have greatest effects on overall ecosystem function 3) protect species with unique (specialized) functions, not easily replaced by other species Ecosystem diversity is also used to refer to the number and variety of interactions in a certain area. Biodiversity underpins ecosystem functioning and the provision of ecosystem services essential for human well-being, it is a central component of many belief systems, world views and identities, it provides for food security, human health, clean air and water, and contributes to local livelihoods and economic High diversity among types of ecosystems means that there will also be a high diversity of species themselves. Genetic diversity Genetic diversity is the sum of genetic information contained in the genes of individuals of plants, animals and micro-organisms. While Earth’s biodiversity is so rich that many species have yet to be discovered, many species are being threatened with extinction due to human activities, putting the Earth’s magnificent biodiversity at risk. the many types of functional units formed by living communities interacting with their environments ecosystem regulation and support services. An ecosystem with fewer species is more likely to thrive. Ecosystem, the complex of living organisms, their physical environment, and all their interrelationships in a particular unit of space. An ecosystem with a high level of biodiversity is more resistant to the environmental change and such ecosystems are rich in a variety of living organisms. Start studying Biodiversity Quiz. Learn ecosystem diversity with free interactive flashcards. Ecosystem diversity deals with the variations in ecosystems within a geographical location and its overall impact on human existence and the environment.. Ecosystem diversity addresses the combined characteristics of biotic properties (biodiversity) and abiotic properties (geodiversity).It is the variation in the ecosystems found in a region or the variation in ecosystems over the whole planet. Which of the following would be an economic benefit of biodiverse ecosystems? d. If conditions become unfavorable, both may crash. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Species Diversity- measure of the diversity within an ecological community. The sea star could be called a(n) ____. 1. increase in diversity often leads to an increase in productivity due to complementary traits among species for resource use, and productivity itself underpins many ecosystem services, 2. increased diversity leads to an increase in response diversity (range of traits related to how In mature ecosystems A. most plants are annuals.

The number of genes range from about 1000 in bacteria, up to … In immature ecosystems A. the species diversity is high. Each species is the repository of an immense amount of genetic information. it allows the population to be more resistant to disruptions. Choose from 500 different sets of ecosystem diversity flashcards on Quizlet. the production of chemicals to manufacture medicines. An ecosystem with high species richness but low evenness would have ____________. Each species is specialized to a type of ecosystem in a particular place. Abiotic factors, or the non-living components of an ecosystem… An ecosystem can be categorized into its abiotic constituents, including minerals, climate, soil, water, and sunlight, and its biotic constituents, consisting of all living members. many different species, with one population being overrepresented in the ecosystem Biodiversity at the community level is known as Biodiversity most oftenrefers to the number of species in a certain area, or the species diversity. A) Species diversity B) Ecosystem diversity C) Genetic diversity D) Species diversity, genetic diversity, and ecosystem diversity are all measures of biodiversity. Recently attention has been focused on global biodiversity and the extinction of species due to human activities. Biodiversity is the variability among living organisms, including terrestrial, marine, and other aquatic ecosystems. The broad differences between ecosystem types and the diversity of habitats and ecological processes occurring within each ecosystem type constitute the ecosystem diversity. It refers not just to species but also to ecosystems and differences in genes within a single species. Ecological diversity is the largest scale of biodiversity, and within each ecosystem, there is a great deal of both species and genetic diversity. There are more uncategorized than categorized species on Earth. Natural selection - The process in which better-adapted individuals - those with a combination of genetic traits better suited to environmental conditions - are more likely to survive and reproduce, increasing their proportion in the … Ecological Diversity- diversity of ecosystems… For example, a coral reef generally has a very great variety of life within it, a greater ecosystem diversity than say Antarctica, which is covered by a sheet of ice [17]. Their customers demand sustainably grown palm oil. Measures all of the different ecosystems/biomes that we have on our planet (e.g. Biodiversity is the variety of all living things; the different plants, animals and micro organisms, the genetic information they contain and the ecosystems they form.

Which of the following is TRUE of isolation and extinction risk? Humans depends on species to survive. This is the total number of species living in an ecosystem. In an ecosystem, living organisms are grouped into producers, consumers, and decomposers, the former representing all plant life, consumers the organisms that eat them and each other, and the latter those scavengers and bacteria that break down dead organic matter.Together, these living components are known as biotic factors. Without the sea star, the mussel population would crowd out other species and take over their ecosystem. Ecosystem diversity is also used to refer to the number and variety of interactions in a certain area. A well-defined ecosystem has strong interactions among its components and weak interactions across its boundaries. Which type of diversity provides the raw material that allows populations to adapt to their environment? In our class, we will use species richness and relative abundance. ecosystems, estuaries, alpine forests, and rocky shorelines has greater ecosystem diversity than does Kansas, which primarily consists of prairies, rivers, and lake ecosystems. Nonlinear science lets you do what makes the most sense and is fluid, and also lets you build off of other people's work and suggestions.
