What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, showing how energy and nutrients flow between different organisms.

Front

What is a food chain?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

Front

What role do producers play in a food web?

Back

Producers, such as plants, create their own food through photosynthesis and serve as the primary energy source for consumers.

Front

What is a consumer in an ecosystem?

Back

A consumer is an organism that cannot produce its own food and must eat other organisms for energy.

Front

What is a decomposer?

Back

Decomposers are organisms, like fungi and bacteria, that break down dead organic matter, returning nutrients to the soil.

Front

What is a detritivore?

Back

A detritivore is an organism that feeds on dead organic matter, helping to decompose it.

Front

What is an apex predator?

Back

An apex predator is a predator at the top of a food chain that has no natural enemies.

Front

How does energy transfer in a food web?

Back

Energy transfer in a food web decreases at each trophic level, with only about 10% of energy being passed from one level to the next.

Front

What is symbiosis?

Back

Symbiosis is a close and long-term interaction between two different species, which can be beneficial, harmful, or neutral.

Front

What are the three types of symbiotic relationships?

Back

The three types of symbiotic relationships are mutualism (both benefit), commensalism (one benefits, the other is unaffected), and parasitism (one benefits at the expense of the other).
