Answer No 1)
Decomposers are an important part of the food chain because they are the main organisms through which materials are recycled. Decomposers break down dead, decaying material so that the materials can be recycled into the Earth. From the Earth, the materials are taken by the plants as nutrients and the cycle continues again and again. Hence, decomposers are an important part of the food chain.
Answer No 2)
Fungi can be found in terrestrial ecosystems.
Snails can be found in terrestrial ecosystems such as a agricultural areas.
Earthworm can be found in terrestrial areas such as a garden.
Pill bug can be found in terrestrial ecosystem such as a forest.
Answer No 3)
Fungi are heterotrophic and have and gain nutrition mainly by absorbing organic compounds from the environment.
Snails usually feed on parts of plants such as a plants stem or roots. Some fungi might also consume fungi or mushrooms.
Earthworms feed on the decaying matter as they eat soil.
Pill bugs, primarily consume plant matter that is either decaying or is already dead and decomposed.
Answer No 4)
Fungi act as decomposers or saprotrophs and recycle nutrients in the ecosystem.
Snails will consume rotting vegetation like moist leaf litter and recycle the nutrients in them.
Earthworm feed on the organic waste in the soil. They break them large organic waste particles so that bacteria and fungi can feed on it and release these nutrients in the atmosphere.
Pill bugs are decomposers. They digest waste like scat as well as decaying matter from dead plants and animals, and then return the essential nutrients back into the soil.
Answer No 5)
Grass ⇒ Grasshopper ⇒ Snake ⇒ Hawk ⇒ Fungi
Thistle ⇒ snail ⇒ Seng Thrush ⇒ Hawk
Soil containing plant remains ⇒ earthworm ⇒ blackbird ⇒ hawk
Soil containing plant remains ⇒ pill bug ⇒ bird ⇒ hawk
