Sea cucumbers and Earthworms play a similar role in their
habitats; both of them break down organic waste matter and play a major role in their
recycling.
Sea cucumbers which live deep in the oceans feed
on tiny algae, marine animals and waste materials. These are broken down into smaller
particles which the bacteria in the oceans can consume, thus recycling them into the
oceanic ecosystem.
Earthworms on land play a similar role.
They burrow into the soil and consume any waste matter that is left behind by other
animals. Earthworms also eat small rocks and solid particles. These are broken down into
very small particles with the organic matter and released. The matter released by
earthworms forms a very nutritious medium for plants to grow in.
