AP Unit 8.2: Energy Flow Through Ecosystems

Which statement is false about endotherms and ectotherms?

Which statement is true about endotherms versus ectotherms?

What is the relationship between mammal size and metabolic rate?

Which statement is true about how energy availability affects reproductive strategies of organisms?

The body temperature data in the table were collected from two different species in the same habitat over the course of the same 15 hours of the same day. Numbers in parentheses are +/- 2 standard errors of the mean.

Determine the average body temperature of species 1 over the course of this experiment.

The body temperature data in the table were collected from two different species in the same habitat over the course of the same 15 hours of the same day. Numbers in parentheses are +/- 2 standard errors of the mean.

Which conclusion is supported by the data in the table?

Blue jays are a species of bird that lives in the eastern and central United States. Students in an AP Biology class observed a population of blue jays near their school eating acorns, berries and seeds.

Ecologists often follow the movement of energy from one trophic level to another. If we consider the energy of the acorns, berries, and seeds to be 100%, what portion of that energy would be expected to be in the biomass of the blue jays that consume these food sources?

Blue jays are a species of bird that lives in the eastern and central United States. Students in an AP Biology class observed a population of blue jays near their school eating acorns, berries and seeds.

The students observe that hawks prey upon the blue jays living near their school. What portion of the energy of the acorns, berries, and seeds would be expected to be in the biomass of the hanks that consume the blue jays?

In the habitat being studied, the total mass of the grass is 8000kg. Calculate the total mass of the hawk population in the habitat.
