Question

if a rabbit consumes 500 calories of plant material, how much of that would be passed on to a hawk in the following food chain? aspen → rabbit → snake → hawk a. 50 b. 5 c. 5,000 d. 500

Answer 1

Answer: 5 calories

Explanation: The producers are self feeders that make their own food by the help of the process known as photosynthesis.

The energy from the producers are transferred from producers to consumers when they eat them. All the energy from the producers are not transferred to consumers.

So, only 10% of the energy are transferred from the previous level to another level. If the rabbit is having 500 calories then the snake will have 50 calories( 10% of 500)

Hawk will get 5 calories which is 10% of 50 calories.  

Answer 2

10% of energy is lost (to heat), for each level of the food chain. So the rabbit would have 500, the snake would have 50 and the hawk would have 5.
