A system formed by the interaction of a community of organisms with their physical environment
One plant or animal - one student is an individual
A group made up of the same kind of individuals living in the same ecosystem - many students make up a population
all the populations that live in the same place
any living thing that can make its own food energy by using sunlight, plus water and carbon dioxide to make food
an animal that eats plants or animals in order to survive - three types - carnivores, herbivores, and omnivores.
animals that eat only plants or producers. Examples are horses, giraffes, squirrels, and rabbits.
animals that eat only other animals. Examples are bobcats, panthers, and lions.

the movement of food energy in a sequence of living things. It always begins with producers.
the consumers that is eaten by another consumer - they are the hunted.

the overlapping of food chains
shows that each level of a food chain passes on less food energy than the level before it. Most of the energy in each level is used at that level so only a little energy is passed on to the next level.
The living parts of an ecosystem - plants and animals
The nonliving parts of an ecosystem - sunlight, air, water, soil
