Energy Flow in Ecosystems

Question 8 • Science 7 B (M12 25/26 S2)

In a rainforest food chain, caterpillars and butterflies eat orchid plants. Toucans eat the caterpillars and butterflies. Leopards eat the toucans.Which statement describes the energy in this food chain?

Answer
A
The leopards gain energy directly from the butterflies.
B
The orchids have the least amount of available energy.
C
The caterpillars gain energy directly from the orchids.
D
The toucans have more available energy than the butterflies.

Explanation

Energy passes from the food an organism eats to that organism. Caterpillars eat orchid plants, so they gain energy directly from the orchids. Leopards do not eat butterflies directly, and energy generally decreases at each step in a food chain, so toucans have less available energy than butterflies.
