Decomposers, which include bugs, mushrooms, worms and bacteria, are nature's recyclers. When a tree dies, decomposers chow down on the dead bark and leaves and turn that old tree into soil, which allows new plants to grow. If trees are cut down and hauled away to make paper, decomposers are left exposed in the hot sun with very little to eat and their population often dies out as a result.

Which of the following is a decomposer?

Kid's Slug

Slimy B-Slug Fact: Banana slugs are slimy for a good reason. Slime causes a predator, such as hawk, to gag on the slug, making it difficult to swallow. The slime also protects the slug's soft body as it slides over rough branches and prickly dead leaves. Slime is a good thing, if you're a slug!
