What is a long-term consequence of deforestation that affects the entire biosphere?     Clearing forest for human land use (commercial, agricultural, residential, etc.)     More lumber for human use in the form of houses, paper, furniture, etc.     Increased amounts of atmospheric carbon that contribute to global warming.     Immediate loss of habitat for a variety of species.

The greatest SINGLE threat to most species of plants and animals is: Question 17 options: - chemical pollution of water and soil - buildup of toxic substances in food webs. - competition from invasive species over-harvesting for human consumption/use. - habitat destruction/alteration

Approaches to protect tropical forests include all of the following strategies EXCEPT: Question 19 options: - banning debt-for-nature swaps - slowing population growth - reforming timber-cutting regulations - reducing poverty through investments in women’s education and family planning - teaching settlers sustainable small-scale agriculture

Someone with a life-centered environmental worldview believes that species exist primarily for the use of humans species are only of value if they are of use to humans all species have value in fulfilling their particular role within the biosphere, regardless of their potential or actual use to humans all species deserve to be protected, but do not have value unless they are useful to humans preserved land should be open for humans to use

Secondary succession is always the result of anthropogenic factors. True or False?

Variety of Plant Life in Texas Ecoregions Ecoregion Trees Shrubs Conifers Succulents Vines Grasses Wildflowers Q 15 2 7 11 18 4 1 6 6 9 14 3 2 5 5 9 13 9 4 4 4 12 15 The table describes the number of the most common plants for ecoregions in Texas. Which statement can best be supported by the information? 16 F Ecoregion Q has a lot of animals that eat the plants. G Ecoregion R has a variety of biotic factors that support the abiotic factors. H Ecoregion S has poor soil quality and extremely high precipitation. J Ecoregion T has the abiotic factors to support the greatest variety of plant life.

Why are land disturbances and the loss of animal habitats for oil sands harmful for the environment? With resources and connections

An effective way to reduce future atmospheric warming would be to reduce international trade protect tropical rainforests and help them to regrow document all of the biodiversity in areas prior to development tightly regulate economic growth reduce infectious diseases spread by animals

What is the relationship between a pioneer species and primary succession?         A pioneer species is an invasive species that causes areas to experience primary succession.          There is not a relationship between a pioneer species and primary succession. The pioneer species only occurs in areas of secondary succession.         A pioneer species is important in an area of primary succession because it can grow and thrive in areas where most other species cannot.          A pioneer species only inhabits areas of primary succession.

In some marine habitats in New England, the population density of lobsters has been depleted due to heavy fishing. When this happens, it often follows that the diversity of species in the biological communities is reduced. Based on this observation, how would you characterize lobsters?     a keystone organism     a decomposer     a crustacean     a superior predator     a producer   The composition of a community refers to the     nutrients available in the soil.     type of succession that occurs locally.     sunlight available to drive the energy needed for metabolism.     extent vegetation covers the ground--a desert has low composition.     types of species adapted to living there.   Small fish sometimes swim very close to large predatory fishes such as sharks. There is no risk since the shark does not feed on these smaller fish. The small fish are able to eat the remains of prey such as seals that the shark rips apart when eating.…
