The earthworm gets nutrients the same way most other animals get nutrients, by eating and digesting them. The earthworm digests dirt and bacteria and enzymes in the dirt in order to utilize the vitamins and minerals it needs to survive.
To process food and extract nutrients.
the crop gives the worm nutrients (food)
Birds prey on earthworms as a food source, using their beaks to locate and extract them from the ground. This interaction plays a crucial role in the ecosystem as it helps regulate earthworm populations and provides birds with essential nutrients.
The excreta of an earthworm is called "cast" or "vermicast." This organic matter is rich in nutrients and beneficial microorganisms, making it an excellent natural fertilizer for soil. Earthworm casts enhance soil structure and fertility, promoting healthy plant growth.
increase intestine surface area for more efficent absorption of digested nutrients
In earthworm, typhlosole is a dorsal flap of the intestine that runs along most of its length. Its function is to increase intestine surface area for more efficient absorption of digested nutrients. In different earthworm families, the typhlosole appears to have multiple origins
The typhlosole is a fold in the intestinal wall of an earthworm that increases the surface area for absorption of nutrients. It helps in the digestion and absorption of food in earthworms by providing more surface area for enzymes to break down food particles and for nutrients to be absorbed.
Nutrients are absorbed by the earthworm's digestive system from the ingested soil and transported by the circulatory system in the blood. The circulatory system consists of blood vessels that deliver these nutrients to all body tissues, including the muscle cells in the body wall. Once in the muscle cells, nutrients are utilized for energy production and other cellular processes.

Earthworm does not have the back bone. Earthworm is invertebrate animal.

lol, are you doing sections 1 and 2 for mollusks and segmented worms?
