Question

The organisms in a food chain are listed in order of trophic level from left to right.

A flowchart: Plant, Grasshopper, Mouse, Snake, Hawk.

Based on the food chain, if a hawk acquires 50 calories of energy, how much energy did the grasshopper get from the plant?

500 calories
5,000 calories
50,000 calories
500,000 calories

Answer 1

Step-by-step explanation:

50,000. Because each trophic level only contributes about 10% of its energy to the next higher up, consuming the other 90% through sustaining its own existance. Thus, for the hawk to consume 50 calories, the snake must have consumed 500, the mouse 5000, and the grasshopper 50,000.
