Decomposers recycle nutrients back into the soil so that they can be taken up by the roots of plants. 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? A worm, bacterium, or fungi would all be acceptable examples of a decomposer.
Fungi is a decomposer. 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.
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? The vulture is a decomposer that could be added to this food chain to complete it. The correct answer is "1 fungi, 2 grass, and 3 cricket".

Possible Answers: A decomposer eats producers. A decomposer is responsible for providing energy to tertiary consumers.
A decomposer is at the top of the food chain and is an apex predator. Correct answer: A decomposer breaks down organic material.
Explanation : A decomposer is an organism that breaks down organic material. Report an Error. Example Question 2 : Movement Of Matter.
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. Correct answer: Break down dead organisms. If decomposers disappeared from a forest ecosystem, wastes as well as the remains of the dead organisms would pile up, and producers plants would not have enough nutrients.
What is an example of a decomposer? What would happen if decomposers were absent from a forest ecosystem? Purple Rose. Oct 9, See the explanation. Explanation: Some examples of decomposers include bacteria , fungi, and some insects. If a media asset is downloadable, a download button appears in the corner of the media viewer.

A food web is all of the food chains in an ecosystem. Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web. Producers, who make their own food using photosynthesis or chemosynthesis, make up the bottom of the trophic pyramid.
Primary consumers, mostly herbivores, exist at the next level, and secondary and tertiary consumers, omnivores and carnivores, follow. At the top of the system are the apex predators: animals who have no predators other than humans. Help your class explore food chains and webs with these resources. Plastic is ubiquitous in our everyday lives.
Some plastics we can reuse or recycle—and many play important roles in areas like medicine and public safety—but other items, such as straws, are designed for only one use. In fact, more than 40 percent of plastic is used only once before it is thrown away, where it lingers in the environment for a long, long time. It often breaks down into smaller and smaller particles, called microplastics, which can be ingested by both animals and people.
Fortunately, there are things we can do to help—like stop using plastic bags, straws, and bottles, recycling when we can, and disposing of waste properly. Use these classroom resources to teach about ocean plastics and check back for more coming later this year! Encyclopedic entry. Humus is dark, organic material that forms in soil when plant and animal matter decays.
When plants drop leaves, twigs, and other material to the ground, it piles up. An illustration gallery and information on the African savannah ecosystem. Join our community of educators and receive the latest information on National Geographic's resources for you and your students.
