Earthworms eat dead plants and animals. When they eat, they also take in soil and tiny pebbles. They take in nutrients from microorganisms in the material they ingest. Earthworms then excrete wastes in the form of casts. Casts are rich in nutrients like nitrogen, phosphorus, and potash.

1 decomposition The process of breaking down material to release nutrients back into the soil. 2  denitrifying bacteria The bacteria that convert nitrates in the soil into nitrogen gas which is released into the atmosphere. 3  egested material Undigested material that has passed out of the alimentary canal or gut.

The nitrogen cycle. Nitrogen compounds found in cells include proteins. Nitrogen from the air is converted into soluble ions that plant roots can absorb. It forms part of nitrogen compounds in the plants, and is then passed from one organism to the next. It is returned to the atmosphere as nitrogen gas. This is the nitrogen cycle. The slideshow shows how the cycle works.

Omnivores are animals that feed on both plants and animals. Examples of omnivores are humans and bears. Saprobes are organisms that get nutrients by breaking down the remains of dead plants and animals. Examples of saprobes are bacteria and fungi.

When plants and animals die, they become food for decomposers like bacteria, fungi and earthworms. Decomposers or saprotrophs recycle dead plants and animals into chemical nutrients like carbon and nitrogen that are released back into the soil, air and water. Bacteria can be found everywhere. They live in the water, in the air and on land.

A decomposer is an organism of decay. These are also called saprobes. They break down the remaines of dead animals and plants, releasing the substances that can be used by other members of the ecosystem. Define and give examples of each of these heterotrophic types: herbivores, carnivores, omnivores, and saprobes.

Producers are organisms, like green plants, that produce organic compounds from inorganic compounds. These are also a type of autotroph. THen green plants, for example, are are eaten by consumers in this case, grazing animals like the zebra.

Split and merge into it. Answer by Rjrox. Confidence votes 21. All bacteria that are called saprophytes break down the remains of dead organisms. These bacteria recycle oxygen, nutrients, and other valuable resources that can be used over by other organisms. THE CORRECT ANSWER: nitrogen compounds.

Recognize that the routes by which the flow of energy and the recycling of matter through the ecosystem occur are called food chains. The ultimate source of energy for life on Earth is the sun. Solar energy is trapped during the process of photosynthesis and converted into a chemical form that we normally call food.

which cycle of life includes the process of decomposers breaking down waste and plant remains and return these compounds into the soil where they can be used by plants?
The nitrogen cycle of life includes the process of decomposers breaking down waste and plant remains and return these compounds into the soil where they can be used by plants.
