How are earthworm adapted to its habitat?
Earthworms are adapted for life underground. Their streamlined shape allows them to burrow through soil. They have no skeletons or other rigid structures to interfere with their movement. Each segment has a number of setae or very small bristles that earthworms use to help them grip the soil as they move.

They eat earthworms, slurping them like spaghetti. Earthworms influence (and benefit) the soil ecosystem in a number of ways: Recycling organic material: Earthworms, along with bacteria and fungi, decompose organic material. Improving soil structure: Earthworm burrows alter the physical structure of the soil.
What is the habitat of earthworm?

It’s the entire neighborhood where an animal gets the food, water and cover it needs to survive. Scientists call this home or place its habitat. For humans, habitat may mean the neighborhood or city in which they live.
Why are worms good for the environment?
By their activity in the soil, earthworms offer many benefits: increased nutrient availability, better drainage, and a more stable soil structure, all of which help improve farm productivity. Worms feed on plant debris (dead roots, leaves, grasses, manure) and soil. Nitrogen in the casts is readily available to plants.
Which habitat do worms prefer?
moist soil
The habitat of the earthworm is moist soil, although some earthworms actually prefer mud, such as the mud that is found along the shores of lakes or swamps. Earthworms can be found in the soil of backyards as well as near bodies of fresh and salt water.

How do you describe earthworms?
An earthworm is a terrestrial invertebrate that belongs to the phylum Annelida. They exhibit a tube-within-a-tube body plan, are externally segmented with corresponding internal segmentation, and usually have setae on all segments. Earthworms are commonly found in soil, eating a wide variety of organic matter.
What best defines a worm?
