Food Chains, Food Webs, Energy Pyramids

Front

What is the primary source of energy for all food chains on Earth?

Back

The Sun.

Front

What happens to the number of plants if a primary consumer is removed from the ecosystem?

Back

The number of plants would increase.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem.

Front

What is the effect of a sudden increase in the cricket population on the grass/flowers population?

Back

Front

What is a food chain?

Back

A food chain is a linear sequence of organisms where each is eaten by the next in the chain.

Front

What role do producers play in a food web?

Back

Producers, like plants, create energy through photosynthesis and are the base of the food web.

Front

What is an energy pyramid?

Back

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

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.
