Ecological diversity is the largest scale of biodiversity, and within each ecosystem, there is a great deal of both species and genetic diversity. A well-defined ecosystem has strong interactions among its components and weak interactions across its boundaries. c. If conditions become unfavorable, both have a better chance of thriving. Humans depends on species to survive. An ecosystem with high species richness but low evenness would have ____________. Biodiversity and Ecosystem Stability Ecosystem diversity - The variety of ecosystems found on Earth. 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. In immature ecosystems A. the species diversity is high. 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. What is NOT a cause of habitat destruction? Which type of diversity provides the raw material that allows populations to adapt to their environment? In mature ecosystems A. most plants are annuals. Increased species biodiversity is also known as species richness. Ecosystem diversity variety of habitats, living communities, and ecological processes in the living world. Biodiversity and Ecosystem Stability Ecological Diversity- diversity of ecosystems… b. Which of the following is NOT an environmental cost of clearing tropical forests? 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. Biodiversity refers to the variety of living species on Earth, including plants, animals, bacteria, and fungi. It reflects the number, variety and variability of living organisms and how these change from one location to another and over time. In our class, we will use species richness and relative abundance. Genetic diversity Genetic diversity is the sum of genetic information contained in the genes of individuals of plants, animals and micro-organisms. Ecosystem, the complex of living organisms, their physical environment, and all their interrelationships in a particular unit of space. The number of genes range from about 1000 in bacteria, up to … In general, places with more varied terrain tend to have more ecosystems than places where topography is more homogeneous. Each species is specialized to a type of ecosystem in a particular place. Ecosystem Diversity Biodiversity is a system in constant evolution, from a viewpoint of species, as well as from viewpoint of an individual organism. You see a bee pollinating a flower. a. many different species, with one population being overrepresented in the ecosystem Biodiversity at the community level is known as D. the efficiency of nutrient recycling is low. High diversity among types of ecosystems means that there will also be a high diversity of species themselves. What is the MOST likely location of a biodiversity hotspot? Ecologists will use more than one index to calculate the level of diversity. ecosystems, estuaries, alpine forests, and rocky shorelines has greater ecosystem diversity than does Kansas, which primarily consists of prairies, rivers, and lake ecosystems. Each species is specialized to a type of ecosystem in a particular place. Learn vocabulary, terms, and more with flashcards, games, and other study tools. The broad differences between ecosystem types and the diversity of habitats and ecological processes occurring within each ecosystem type constitute the ecosystem diversity. An ecosystem with fewer species is more likely to thrive. Their customers demand sustainably grown palm oil. Most people are familiar with ecosystems in terms of where they are, that is, in terms of ecosystem distributions. Difference between 'reproduction' of fire and reproduction of life, Fire 'reproduces' by spreading around but life passes on genes and evolves, Variety of life in the world or an environment, Ecosystem Diversity - Different types of ecosystems organisms live in, like rainforests or coral reefs, 1) Ecosystems will be more stable, and if one collapses it harms people because they can lose a food source or resource, Number of species present in a sampled environment, How equal the numbers of defferent species in a sampled environment are. Differences between linear and nonlinear scientific methods. the production of chemicals to manufacture medicines. Most people are familiar with ecosystems in terms of where they are, that is, in terms of ecosystem distributions. Learn ecosystem diversity with free interactive flashcards.
