True

False

Question 33

Hydroelectric power is considered a renewable energy source.

True

False

Question 34

Question 35

Which statement best contrasts environmentalism with ecology?

Ecology is the study of the environment; environmentalism is the study of ecology

Ecologists study organisms in environments that have been undisturbed by human activities; environmentalists study the effects of human activities on organisms.

Environmentalism is devoted to applied ecological science; ecology is concerned with basic/theoretical ecological science.

Environmentalists are only involved in politics and advocating for protecting nature; ecologists are only involved in scientific investigations of the environment.

Question 39

Why would increasing the amount of sunlight increase carnivore biomass?

It will increase the amount of energy, and therefore the amount of biomass, in the system.

None of these is correct.
