Which type of organism helps recycle nutrients in the ecosystem by breaking down the tissues of dead organisms?
Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.
Which type of organism has the role of recycling nutrients within the system?
Decomposers are organisms that consume dead organisms and other organic waste. They recycle materials from the dead organisms and waste back into the ecosystem. These recycled materials are used by the producers to remake organic compounds.
What makes an ecosystem healthy?
A healthy ecosystem consists of native plant and animal populations interacting in balance with each other and nonliving things (for example, water and rocks). Healthy ecosystems have an energy source, usually the sun. Decomposers break down dead plants and animals, returning vital nutrients to the soil.
What kind of organisms need oxygen for respiration?
Most ecosystems contain aerobic microbes and animals that require atmospheric oxygen for respiration, and even exotic ecosystems dominated by anaerobic bacteria include oxygen as an atomic component of molecules such as carbon dioxide, nitrate and water.
Where does oxygen come from in an ecosystem?
Oxygen is an essential and pervasive element in virtually all biological environments. Most ecosystems contain aerobic microbes and animals that require atmospheric oxygen for respiration, and even exotic ecosystems dominated by anaerobic bacteria include oxygen as an atomic component of molecules such as carbon dioxide, nitrate and water.
Who are the living organisms in an ecosystem?
The living organisms in an ecosystem can be divided into three categories: producers, consumers and decomposers. They are all important parts of an ecosystem. Producers are the green plants. They make their own food.
Which is the first organism in a food chain?
C. Producers provide energy for other producers in the ecosystem. D. Producers provide energy for consumers and other producers in the ecosystem. A. Producers provide energy for consumers in the ecosystem. Which is the first organism in a food chain?
