Question

What is a decomposer in the food chain?

Answer

A decomposer is an organism that breaks down organic material. This includes the remains of dead organisms. Bacteria, worms, snails, slugs, and fungi are types of decomposers. All organisms undergo decomposition after death.

What is the role of a decomposer in an ecosystem?

Answer

A decomposer is an organism that feeds on and breaks down dead plant or animal matter, making organic nutrients available to the ecosystem. Often a decomposer is a bacterium, fungus, or invertebrate. Decomposers play a critical role in the flow of energy through an ecosystem. Decomposers make vital nutrients available to an ecosystem’s primary producers—usually plants and algae.

What would happen in a food chain if decomposers were removed?

Answer

If decomposers were removed from a food chain, there would be a break down in the flow of matter and energy. Waste and dead organisms would pile up. Producers would not have enough nutrients because, within the waste and dead organisms, nutrients would not be released back into the ecosystem.

Question

If Jessa is making a model of a food chain and needs to include decomposers, what type of organism could she use as an example?

Answer

A decomposer is an organism that feeds on and breaks down dead plant or animal matter, making organic nutrients available to the ecosystem. Often a decomposer is a bacterium, fungus, or invertebrate. Decomposers play a critical role in the flow of energy through an ecosystem. Decomposers make vital nutrients available to an ecosystem’s primary producers—usually plants and algae. A worm, bacterium, or fungi would all be acceptable examples of a decomposer.

Question

How do decomposers assist producers in moving matter in the food chain?

Answer

Decomposers play a vital role in keeping the food chain functioning properly. As decomposers break down the remains of dead organisms and produce waste, nutrients are recycled back into the soil for producers (plants) to absorb through their roots. Without decomposers, there would be a buildup of debris, remained, and a lack of nutrients in the food chain.

Question

Which organism below is an example of a decomposer?

Answer

Fungi is a decomposer. Decomposers play a vital role in keeping the food chain functioning properly. As decomposers break down the remains of dead organisms and produce waste, nutrients are recycled back into the soil for producers (plants) to absorb through their roots. Without decomposers, there would be a buildup of debris, remained, and a lack of nutrients in the food chain.

Question

Composting takes advantage of the natural process of decomposition by

Answer

Composting is a form of decomposition and takes advantage of the natural bacteria, fungi, and organisms that break down waste. Many people will collect kitchen scraps and debris, let the organic matter break down, and then spread it in gardens or potted plants because it is rich in nutrients. Decomposers play a vital role in keeping the food chain functioning properly. As decomposers break down the remains of dead organisms and produce waste, nutrients are recycled back into the soil for producers (plants) to absorb through their roots. Without decomposers, a buildup of debris remained and a lack of nutrients in the food chain.

Answer

The vulture is a decomposer that could be added to this food chain to complete it. A decomposer is an organism that feeds on and breaks down dead plant or animal matter, making organic nutrients available to the ecosystem. Often a decomposer is a bacterium, fungus, or invertebrate.

Question

Which of the following is an example of a 1) decomposer, 2) producer, and 3) a consumer?

Answer

A decomposer is an organism that breaks down organic material. This includes the remains of dead organisms. Bacteria, worms, snails, slugs, and fungi are types of decomposers. All organisms undergo decomposition after death. The correct answer is "1) fungi, 2) grass, and 3) cricket".
