NEET BIOLOGY

Detailed explanation-1: -More importantly, decomposers make vital nutrients available to an ecosystem’s primary producers-usually plants and algae. Decomposers break apart complex organic materials into more elementary substances: water and carbon dioxide, plus simple compounds containing nitrogen, phosphorus, and calcium.

Detailed explanation-2: -Decomposers in ecosystems act as environmental cleaners by decaying dead plants and animals. They aid in the recycling of nutrients. They make room for a new life in the biosphere by decaying the dead.

Detailed explanation-3: -However, micro-organisms such as bacteria, fungi, and actinomycetes–even though they go unnoticed in your compost pile–are responsible for most of the organic material breakdown. They are chemical decomposers because they use chemicals in their bodies to break down organic matter.

Detailed explanation-4: -Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren’t in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.

Detailed explanation-5: -Bacillus subtilis and Pseudomonas fluorescens are examples of decomposer bacteria. Additions of these bacteria have not been proved to accelerate formation of compost or humus in soil. Rhizobium bacteria can be inoculated onto legume seeds to fix nitrogen in the soil.
