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 the starting point of all food chains?

Back

All food chains begin with the Sun.

Front

How does a meteor impact the food chain?

Back

A meteor can cause dust to block sunlight, disrupting photosynthesis and leading to a collapse in food chains.

Front

What role do primary consumers play in an ecosystem?

Back

Primary consumers are herbivores that eat producers (plants) and convert the energy from plants into a form that can be consumed by secondary consumers.

Front

What is the significance of the Sun in an ecosystem?

Back

The Sun provides the energy necessary for photosynthesis, which is the foundation of most food chains.

Front

What happens to energy as it moves up the food chain?

Back

Energy decreases as it moves up the food chain due to energy loss at each trophic level, typically around 90% is lost.
