Question

The best arrangement of an energy system consisting of hawks, snakes, mice and grasses is

• A. Grass $\to$ mouse $\to$ snake $\to$ hawks
• B. Grass $\to$ snake $\to$ mouse $\to$ hawks
• C. Grass $\to$ mouse $\to$ hawks $\to$ snakes
• D. Mouse $\to$ snake $\to$ hawks $\to$ grass

Answer 1

The correct option is A Grass $\to$ mouse $\to$ snake $\to$ hawks

The food chain illustrated above indicates, that the mouse receives its energy from the grasses, the snake receives its energy from the mouse and the hawk receives its energy from the snake. The arrows show the transfer of energy from one organism to the next, therefore the arrow points at the organism that is receiving the energy.

Grass (Producer) -> Mouse (1st order consumer) -> Snake (2nd order consumer) -> Hawk (3rd order consumer).

Thus, the correct answer is option A.
