Question

If the tertiary consumers in your ecosystem have 420 kCal of energy and the trophic efficiency is 10%, determine the amount of energy in the other trophic levels.

Answer 1

Answer:

Tertiary consumers: 420 kcal

Secondary consumers: 4 200 kcal = tertiary consumers x 10

Primary consumers: 42 000 kcal = secondary consumers x 10

Primary producers: 420 000 kcal = primary consumers x 10

Explanation:

The trophic efficiency is 10 %, therefore, each trophic level will have 10 times more/less energy than the one up/down as you can see in the picture.

Hope this will help :)
