Some scientists believe we are in the midst of a new phase of mass extinction, influenced by human behavior, threatening the earth’s biological diversity and contributing to widespread ecological crises. How can the study of non-human species help shape human responses to these potential threats?

In 2011, approximately 23% (1138) of mammal species and 12% (1253) of bird species were globally threatened. These two groups have been thoroughly studied. The case with other groups of organisms is not well known. A large number of the threatened species are concentrated in tropical rain forest habitats, where biodiversity is high. Which of the following data options could be used to determine the cause of biodiversity decline in tropical habitats?

According the Red Queen hypothesis, a species must continually evolve if it is to continue to be able to survive. True False

Consider this claim: Changes in environmental conditions always result in new ecosystems and loss of biodiversity characterized by an increase in the number of some species, the evolution of new species, and the extinction of some species. Use what you have learned from the lesson, as well as reliable and reputable resources, to evaluate this claim. Use at least three examples from the lesson and other sources to support the valid ideas in the claim and refute the invalid ones. Add a list of your resources at the end of your response. Then, draw a conclusion about the stability of ecosystems, how and what can affect the stability of ecosystems, and how changes in the environment may affect the types and number of living things in an ecosystem.
