Energy & Ecosystems Review

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem, showing how energy and nutrients flow through different trophic levels.

Front

What is the correct order of energy transfer in a food chain?

Back

The correct order of energy transfer in a food chain is from producers to primary consumers to secondary consumers and so on.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil, which supports plant growth.

Front

If there are 1000 Kcal available at the producer level, how much energy is available at the secondary consumer level?

Back

10 Kcal.

Front

Which organisms have the most energy available in an energy pyramid?

Back

Producers have the most energy available in an energy pyramid.

Front

Define producers in an ecosystem.

Back

Producers are organisms, typically plants, that can make their own food through photosynthesis, forming the base of the food chain.

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 is the difference between a food chain and a food web?

Back

A food chain is a single pathway of energy flow, while a food web consists of multiple interconnected food chains.

Front

What is the role of herbivores in an ecosystem?

Back

Herbivores are primary consumers that eat plants, transferring energy from producers to higher trophic levels.

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation showing the flow of energy at different trophic levels in an ecosystem.
