Question

35 in feeding relationship models like food chains and food webs, the arrow points in the direction of
a energy flow
b producers
c who got eaten
d who gives energy

Explanation:

In food chains and food webs, arrows represent the direction of energy transfer. Energy flows from one organism to another as one is consumed by another. Producers are at the start of the chain but the arrow doesn't point to them in terms of general direction in the model (it points away from them as energy is passed on). "Who got eaten" would be the opposite direction of the arrow (arrow points from the eater to the eaten in terms of energy flow conceptually, but more accurately it's about energy movement). "Who gives energy" - the arrow points towards who receives energy not who gives (the giver is at the tail of the arrow). So the arrow points in the direction of energy flow.

Answer:

A. energy flow
