What does a food chain represent?
How all living organisms within a habitat are connected.
All of the things that a particular animal eats.
How plants create their own food.
A single path of energy transfer within a habitat.
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.

How much energy is available to be passed on to the next trophic level in an ecosystem?
100%
10%
50%
75%
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.
