Question

A tiny rocky island in the South Pacific is home to a very small food chain. Coconut palms grow on the island and drop coconuts. The coconuts are eaten by coconut crabs. The coconut crabs are then eaten by seals. According to an ecological energy pyramid, the seals would receive about ___________ of the energy from the coconuts.

A) 0.1%
B) 1%
C) 10%
D) 100%

Answer 1

The seals would receive about (B.) 1% of energy from the coconuts.

Answer 2

The correct answer is (b) 1%

Step-by-step explanation:

Represented in an ecological energy pyramid, the seals would be in the third position from the bottom as secondary consumers.

In this example, the base of the pyramid will be represented by the coconut palms, the primary producers, also known as autotrophs, which create their food by taking their energy from non-living sources of energy, like the sun.

The second level consists of primary consumers. Herbivores feed solely on primary producers, in this case, the coconut crabs.

The third level would be the secondary consumers, usually carnivores and omnivores, in this case, the seals.

In this example, as seals would be the secondary consumers located at the third level of the pyramid from the bottom, they will receive about 1% of energy.

I hope it helps!
