Grade 7 Energy Flow

Front

What are autotrophs?

Back

Autotrophs are organisms that produce their own food, primarily through photosynthesis. Examples include plants and some bacteria.

Front

Which organisms are classified as producers?

Back

Producers are organisms that make their own food, such as plants and algae.

Front

What is a top predator?

Back

A top predator is an animal that has no natural enemies and is at the top of the food chain, such as a hawk.

Front

What is the energy transfer efficiency from one trophic level to the next?

Back

The efficiency of energy transfer from one trophic level to the next is roughly 10%.

Front

What role do herbivores play in the energy pyramid?

Back

Herbivores are primary consumers that eat producers (plants) and are located above producers in the energy pyramid.

Front

What are consumers?

Back

Consumers are organisms that cannot produce their own food and rely on eating other organisms for energy.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic material, returning nutrients to the soil and helping to recycle energy.

Front

What is the primary source of energy for most ecosystems?

Back

The primary source of energy for most ecosystems is sunlight, which is harnessed by producers through photosynthesis.

Front

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.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains that illustrates how different organisms are related in an ecosystem.
