'''Earthworms''' eat dead organic matter. "Worm farms" (vermiculture) produces highly effective fertilizers called ''vermicompost'' (solid) and ''vermitea'' (liquid).

==Biology==
Earthworms can have a lifespan of up to fifteen years. They are hermaphroditic, and reproduction results in a cocoon producing up to seven young. They will die at temperatures below freezing or above 32 degrees Celsius.

Earthworms regulate their own numbers within the limits of the available food supply.

==Varieties==
There are about 4700 described species of earthworm, which for agricultural purposes can be divided into three groups:
*''Anecic'' earthworms build permanent burrows fairly deep into the soil and drag food down into their burrows.
*''Endogeic'' earthworms build temporary burrows in shallow soil.
*''Epigeic'' earthworms live in mats of decomposing plant matter on top of the soil. Only epigeic earthworms are suitable for use in vermiculture.

==Open issues==
*Can earthworms be transported from Earth to Mars?
**What are their minimum nutrient requirements in microgravity?
