What are the two possible

destinations for the food that is

absorbed by the gut?

F 100

Respiration and growth

F 100

If 1,347 g/hr is absorbed by the gut of an animal and 900 g/hr is used in respiration… then how

many g/hr. goes to growth?

F 200

447 g/hr.

F 200

F 300

• A whale shark has GROWTH EFFICIENCY of 13%. Is that good, average or bad? Explain.

13% would be could good because the

average absorption efficiency is 10%

F 300

Is an animal ingests 900kg/day and 395

kg/day are absorbed, what is

the ABSORPTION EFFICIENCY?

F 400

F 400

• 395/900 X 100 = 43.8%

Solve for growth and absorption efficiencies.

How would the behavior of pelagic and benthic organisms differ based

on where they live?

Click on screen to continue

Pelagic organisms must swim to fight gravity.

Benthic organism rest on the bottom and may need

to burrow.
