They are a major food source in many ecosystems

They are decomposers (break down dead organisms)

Detailed explanation-1: -Bacteria and fungi are called decomposer because they break down the dead and decaying organic matter into a simpler substance. It provides the nutrients back to the soil.
Detailed explanation-2: -Fungi and bacteria are essential to many basic ecosystem processes. Some types of fungi and bacteria can break down fallen wood and litter returning nutrients to the soil. Other types can fix nitrogen in the soil and help plants get nutrients from the soil.
Detailed explanation-3: -They perform a valuable service as Earth’s cleanup crew. Without decomposers, dead leaves, dead insects, and dead animals would pile up everywhere. Imagine what the world would look like! More importantly, decomposers make vital nutrients available to an ecosystem’s primary producers-usually plants and algae.
Detailed explanation-4: -Bacteria and fungi are called decomposers because bacteria and fungi break down the dead and decaying organic matter into simpler substances and provide the nutrients back to the soil. Advantages of decomposers to the environment:i They act as natural scavengers. ii They help in recycling of nutrients.
Detailed explanation-5: -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.
