What is
Biodiversity
All organisms of the SAME species in an ecosystem (same location)
What is
a population
How different species in an ecosystem interact
Symbiosis
Organisms that eat other organisms for energy.
Heterotrophs
All the interconnecting food chains in an ecosystem.
What is a
Food web
The study of how organisms interact with each other and the environment.
What is
Ecology
All interacting populations in an ecosystem
What is a
Biological Community
One interacting organism benefits and the other isn't benefited or harmed
Commensalism
An animal that feeds on dead things
What is a
scavenger or detritivore

Biotic Factor
The role of an organism (what it eats, what eats it and other things it does for the ecosystem)
Niche
Organisms that can make their own food.
Autotroph
A group of organisms in an ecosystem that share the same energy level of the food web.
What is
a Trophic level
