The arrows in a food chain or web represents what?

• They point to the organism that is being eaten.

• It shows how sunlight flows within an ecosystem.

• They show what direction the energy is flowing between organisms. 

• They represent how water is transferred within a habitat.

What does a food web represent?

• All connections of energy flow throughout all organisms in a habitat.

• The specific ways that mutualism is carried out.

• A single pathway or energy flow between organisms. 

• How carnivores get their food.

An energy pyramid represents what?

• How much sunlight is available for the ecosystem to use. 

• How much energy a particular organism needs. 

• How much energy is needed to build a pyramid.

Why is there a limited amount of energy that can be passed on to the next feeding level?

• There is never enough sunlight available. 

• Some ecosystems have limited resources. 

• Organisms use some of the energy they get from eating.

• All the energy is available to be passed on.

Why might an organism have more than one arrow coming from them in a food web?

• More than one organism may eat them. 

• They may eat more than one other organism. 

• This organism gets its energy from multiple sources. 

• They have no resources available to them.
