Chapter 40, Problem 1PIT
Summary Introduction
To add:
The terms population, community or ecosystem along the right edge of figure 40.27. Connect each treat to biodiversity to one of the new boxes and explain each new connecting phrase that explains the way in which threat explains the effect on biodiversity.
Concept introduction:
The variety of organisms on earth defines biodiversity. The biodiversity is destroyed by habitat destruction, pollution and climate change, invasive species and over-exploitation.

NOTE: The image you need to see in order to answer this question is attachedA developer owns the property encompassing the three habitats above. By law, one of the habitats must be left intact to satisfy the zoning laws. The developer works with an environmental engineer to choose which of the habitats should be saved. The environmental engineer suggests that Site C should be saved. Which of the following choices best justifies this decision?Responses
A) Site C has greater species richness and species evenness than either Site A or Site B. This will promote the maximum sustainability for future generations of animals. B) Site C is tied with Site A for greatest species richness, but unlike Site A, it has representative species from all 3 of the sites within it. C) Site C not only contains the greatest number of species, it also has the greatest genetic diversity within each species. D) Site C has more unique species in it than either Site A or Site B
In a paragraph with complete sentences, describe two human-caused threats to biodiversity.
