What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem, starting from producers to various levels of consumers.

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, showing how different organisms are related through feeding relationships.

Front

What role do microorganisms play in an ecosystem?

Back

Microorganisms decompose organic matter, recycle nutrients, and help maintain soil health, making them essential for ecosystem functioning.

Front

Where does the energy in a food web originate?

Back

The energy in a food web comes from the sun, which is captured by producers through photosynthesis.

Front

What is an estuary?

Back

An estuary is a coastal area where freshwater from rivers meets and mixes with saltwater from the ocean, creating a unique brackish water ecosystem.

Front

What are decomposers?

Back

Decomposers are organisms, such as bacteria and fungi, that break down dead organic material, recycling nutrients back into the ecosystem.

Front

What is the difference between producers and consumers?

Back

Producers are organisms that make their own food through photosynthesis (like plants), while consumers are organisms that eat other organisms for energy.

Front

What is a scavenger?

Back

A scavenger is an animal that feeds on dead or decaying organic matter, helping to clean up the environment.

Front

Give an example of a producer in a food chain.

Back

An example of a producer is a plant, such as grass or a tree, which converts sunlight into energy.

Front

What is a primary consumer?

Back

A primary consumer is an organism that eats producers; for example, a rabbit that eats grass.
