Organisms that decompose organic matter
Animals that consume other organisms
What role do decomposers play in an ecosystem?
Decomposers are primary consumers in the food chain.
Decomposers compete with plants for sunlight.
Decomposers produce energy for plants.
Decomposers recycle nutrients and help maintain ecosystem balance.
Explain the concept of a food chain and its significance.
A food chain only includes plants and ignores animals.
A food chain is a linear sequence of organisms that shows how energy and nutrients flow through an ecosystem, highlighting the interdependence of species.
A food chain represents the physical structure of an ecosystem without any relationships.
A food chain is a circular diagram of species without any energy flow.
How do energy and nutrients flow through an ecosystem?
Energy is created by consumers and lost by producers.
Energy flows from producers to consumers and decomposers, while nutrients cycle through the ecosystem.
Decomposers are the primary source of energy in ecosystems.
Nutrients flow in a linear path without recycling.
