Organisms That Feed on Dead Matter Are Called
All 5th Grade Science Resources
What is a decomposer in the food chain?
Possible Answers:
A decomposer eats producers
A decomposer is at the top of the food chain and is an apex predator
A decomposer is responsible for providing energy to tertiary consumers
A decomposer breaks down organic material
Correct answer:
A decomposer breaks down organic material
Explanation:
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?
Possible Answers:
Bring nutrients to producers and consumers
To capture the energy of the Sun for plants to make food
Produce oxygen for consumers
Break down dead organisms
Correct answer:
Break down dead organisms
Explanation:
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?
Possible Answers:
Final consumers will have to start eating producers.
Primary consumers will have nothing to eat and starve.
Producers would not have enough nutrients, and waste would pile up.
The Sun will direct its energy towards other organisms in the food chain.
Correct answer:
Producers would not have enough nutrients, and waste would pile up.
Explanation:
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.
How do decomposers assist producers in moving matter in the food chain?
Possible Answers:
Decomposers recycle nutrients back into the soil so that they can be taken up by the roots of plants.
Decomposers distract many of the primary consumers from threatening or eating the producers.
Decomposers attract more sunlight which gives producers the energy they need to make food.
Decomposers do not help producers in any way; in fact, they are harmful to them.
Correct answer:
Decomposers recycle nutrients back into the soil so that they can be taken up by the roots of plants.
Explanation:
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.
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?
Possible Answers:
Bacteria
Worm
Fungi
All of the choices are correct
Correct answer:
All of the choices are correct
Explanation:
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.
Organisms that feed on the remains or wasteof otherorganisms are known as ___________.
Possible Answers:
decomposers
consumers
producers
predators
Correct answer:
decomposers
Explanation:
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.
Which organism below is an example of a decomposer?
Possible Answers:
Osprey
Plankton
Fungi
Oak tree
Explanation:
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.
Composting takes advantage of the natural process of decomposition by
Possible Answers:
creating clean drinking water for humans, plants, and animals.
decreasing the Earth's temperature.
releasing harmful chemicals into the atmosphere.
returning energy and nutrients to the environment.
Correct answer:
returning energy and nutrients to the environment.
Explanation:
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.
In the graphic below, a food chain is modeled. The decomposer has been removed from the food chain. Which organism below could be the decomposer in this food chain?
Correct answer:
Explanation:
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. 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.
Which of the following is an example of a 1) decomposer, 2) producer, and 3) a consumer?
Possible Answers:
1) grass, 2) cricket, and 3) vulture
1) mushroom, 2) rose bush, and 3) palm tree
1) fungi, 2) grass, and 3) cricket
1) osprey, 2) snake, and 3) frog
Correct answer:
1) fungi, 2) grass, and 3) cricket
Explanation:
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".
