Answer:
B.
Explanation:
Energy flows from producers to one or more levels of consumers. Think of it this way:
A banana tree grows in the forest.
A monkey eats the bananas off of the tree, it now consumes the energy provided by the banana.
(whatever animal kills monkeys) kills the money for food, they have now consumed the energy of the monkey, as well as the banana the monkey has eaten previously.
The web continues, and energy continues to be distributed to each level of consumer, all starting with a single producer.
