5th Grade Unit 2 Energy and Matter in Ecosystems

Front

What is an ecosystem?

Back

An ecosystem is something that is made up of living and non-living things and their interactions.

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 a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem.

Front

What is an energy pyramid?

Back

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

Front

What are producers?

Back

Producers are organisms that make their own food, usually through photosynthesis, like plants.

Front

What are consumers?

Back

Consumers are organisms that eat other organisms for energy, including herbivores, carnivores, and omnivores.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organisms and waste, returning nutrients to the soil.

Front

How does energy flow in an ecosystem?

Back

Energy flows from producers to consumers and then to decomposers in a one-way direction.

Front

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

Back

A food chain shows a single pathway of energy flow, while a food web shows multiple interconnected pathways.

Front

What is the significance of the energy pyramid?

Back

The energy pyramid illustrates how energy decreases as it moves up trophic levels, with fewer organisms at higher levels.
