What role do earthworms play in the food chain?
Worms are part of a special group of species that eat dead or decaying organic matter. They are called decomposers. Decomposers are very important in our food chain, because they recycle the energy, and help us to start all over again!
How do earthworms help the Earth?
As they move through the soil, earthworms loosen and mix it up, helping to aerate and drain it. This brings nutrients to the surface, making the soil more fertile, and helps prevent flooding and erosion. 3) Earthworms are barometers of soil health and toxicity.
What are four benefits of an earthworm?

What is the role of earthworms in agriculture?
Earthworms have the ability to eat and mix large amount of soil and organic matter and deposit it in the form of casts. They also enhance incorporation and decomposition of organic matter, increase soil aggregate stability, improve porosity and water infiltration, and increase microbial activity.
What is the role of earthworms in agriculture What is vermicompost?
Answer: Earthworms turn the soil up and down which results in the turning of the humus . This fertilizes the the soil. Vermicompost is a type of composting which is done by using various worms.
How do earthworms impact the amount of biomass an ecosystem can support?
They create persistent soil structures enriched by nutrients that improve the conditions for plant growth and modify competition between plant species. … Late successional plants profited from the reduction of early successional plants and increased their biomass. This increase was promoted by the earthworm presence.
What is the economic importance of earthworm?
They are being used presently in vermiculture to produce high-quality manure. They are also used as baits to catch fish. They keep interchanging the topsoil with the layer just below, thereby increasing soil fertility. The excreta of earthworms is rich in nitrogenous matter and is required for plant growth.
How do earthworms return nutrients to the ecosystem?
Earthworms also take nutrients down through the soil profile, bringing them into closer contact with plant roots. … This brings water and soluble nutrients down to plant roots. Burrowing also improves soil aeration (important for both plants and other organisms living in the soil) and enhances plant root penetration.
