Which is a decomposer?
A
rabbit
B
worm
C
dirt
D
flower
Explanation: 

Detailed explanation-1: -Most decomposers are microscopic organisms, including protozoa and bacteria. Other decomposers are big enough to see without a microscope. They include fungi along with invertebrate organisms sometimes called detritivores, which include earthworms, termites, and millipedes.

Detailed explanation-2: -They feed on dead organic matter. These organisms break down this organic matter into simple forms within their body and excrete extra as worm castings. They help in the recycling of nutrients in the ecosystem.

Detailed explanation-3: -Marine worms These worms crawl around the sea bed and rocks eating up decaying matter, creating more nutrients for the ocean ecosystem. As these worms are larger than the bacteria and most fungi, they are called ‘macro decomposers’.

Detailed explanation-4: -Earthworms are super decomposers. If we did not have decomposers, our ecosystems would be a mess and soon fail. Decomposers take nutrients trapped in dead material and return it back to the soil. This allows nutrients to be used by the living organisms.
