Answer:
8
Step-by-step explanation:
According to the 10% law of energy transfer,
only about 10% of energy will be transferred to
the successive level from the previous trophic
level. Therefore according to this law carrot will
have the highest energy level as it is present at
the lowest trophic level.
Then it will transfer 10% of its consumed energy
to the rabbit and then snakes will get 10%
energy of rabbit after consuming it. Therefore if
the energy amount is given it can be calculated
by dividing it by 10 for upper trophic level.
So if a rabbit receives 80 calories of energy
from eating carrots it will pass only 8
(80/10=8) calory of energy on to a snake.
Therefore the correct answer is 8 calories
