yes. they help humans food grow which helps the humans by not starving them. Without food humans could not live.If your thinking about animals, animals need plants too, so without plants humans could not live.
They are called friends of farmers because their excretement makes the soil very fertile. Moreover they dig the soil for their food and bring the humus upwards which is good for plants.
Earthworms play an important role in the creation of healthy, productive "living" soils. Without them, we couldn't eat vegetables and fruits!! Or even breathe! Because they help trees! The early ancestors of the earthworms were partly responsible for ending the global ice age billions of years ago. The relentless burrowing deep in the ocean floor, where the wastes & fossils of organisms accumulated within the sediments, spawned the recycling of carbon nutrients and the formation of carbon dioxide gas. The collective release of CO2 into the Earth's atmosphere generated a greenhouse effect which inevitably warmed the planet to habitable temperatures for later descendants.
Provide most of the organic matter that gets broken down to form humus.
plants and humus
Organic matter transformates into humus. For more information on this process, check this link: http://en.wikipedia.org/wiki/Humus
Humus is formed when organic material (such as leaves , dead animals etc) is disgraded by a combination of fungi,bacteria,microbes and other animals((earthworms for example) that reside in the soil.
they aerate soil and eat organic matter and turn it into plant food
bacteria, earthworms or mites
humus soils
Earthworms do most of the work of mixing humus with other materials in soil. Earthworms and burrowing animals also help aerate, or mix air into, the soil.
Earthworms are the main contributors to enriching and improving soil for plants, animals and humans. Earthworms eat the soil which has organic matter such as decaying vegetation or leaves. After organic matter is digested, the earthworm releases waste from their bodies called castings. Castings contain many nutrients that plants can use.
