What is a population?
One individual member of a species
a group of individuals of the same species that live in the same area
a community of different species and their environment
Which is an example of an ecosystem?
An area of cold climate and communities of different species
one elk
a group of elks living together in the same area
elks, snow rabbits, and owls living in the same area
Which definition best fits the term BIOTIC?
The study of the interactions between animals and their environment
Factors in the environment that are considered not alive
Factors in the environment that are considered living or the remains of living things
One species benefits, the other is unaffected
symbiosis
parasitism
mutualism
commensalism
Honey guide birds alert and direct badgers to bee hives. The badgers then expose the hives and feed on the honey first. Then, the honey guide birds eat as well.

Scavengers
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.
Grass > Grasshopper > Bird > Snake
Decomposer
This is an organism that breaks down and gains nutrients from dead organisms.
Predator
This is an animal that lives by preying on other animals.
Producer
This is an organism that supplies matter and energy, also known as an autotroph.
Consumer
This is an organism that relies on other organisms for its food and energy supply; heterotroph
Parasite
This is an organism which feeds on, but usually does not kill, a larger organism
