B. Biodiversity can be exploited indefinitely for the profit of humans.
C. Other species have inherent value and humans have a moral obligation to protect them.
D. Biodiverse ecosystems provide ecosystem services that sustain all life on Earth.
E. Biodiversity provides emotional and physical health benefits by providing places for humans to visit for wonder, insight, and exercise.
Which of the following statements about ecology is correct? CHECK ALL THAT COULD BE CORRECT
A)Ecological studies may involve the use of models and computers.
B)Ecology is the study of the interactions between biotic and abiotic aspects of the environment.
C)Ecology is a discipline that never considers natural selection and evolutionary history
D)Ecologists may study populations and communities of organisms.
E)Ecology spans increasingly comprehensive levels of organization, from individuals to ecosystems.
(15)The text book gives many details about problems with the threats to biodiversity on planet
Earth, but one problem which may be inherent in their analysis is (a) they fail to note that
biodiversity loss involves population declines (b) they fail to consider human beings as part of
the ecosystems that they survey (c) they fail to note that extinction is reversible (d) they fail to
point out that if trends continue, we may see the extinction of more than half of all species
