Sun
This type of consumer eats only plants.

Carnivore
Scientists use this tool to classify organisms based on physical characteristics.
Dichotomous Key?
This term describes all the organisms of the same species living in the same place.
Population
In an energy pyramid, this group of organisms has the greatest amount of energy.
Producers
This type of consumer, like a grizzly bear, eats both plants and animals.
Omnivore
As a frog grows from a tadpole to an adult, this "role" it plays in the community changes. What is this role called?
Its niche.
Classification is based on observing these three things: patterns, differences, and...
