Atiny 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 that the crabs receive.

The seals would receive about 1% the amount of energy as the crabs.

Explanation:

The seals would receive about 1% the amount of energy as the crabs. The 10% rule says that as you move through an energy pyramid, the available energy decreases by about 90%, leaving 10% available energy for the next trophic level. Since the energy moved through two tropics levels, there is only about 1% available: 100% to 10% to 1%.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
