Biotic factors
large region with similar climate and life
Biome

Prey
one species that live in an area at the same place at the same time
Population
Carnivore

5 Examples of Biomes
varying answers (tundra, grassland, ocean, rainforest, desert, boreal forest, etc)
factors in an ecosystem that limit the growth of a population
Limiting factors
wide range of organisms that live in the same area at the same time
Community

Parasitism
the amount of organisms in a specific area
Population Density
eats both plants and animals
Omnivore
eats plants
Herbivore
number of organisms that die in a given period of time
death rate
interaction in which both organisms benefit
Mutualism
make their own food
Producers (heterotrophs)
a certain number of organisms an ecosystem can hold
Carrying Capacity
organisms that cannot make their own food
Heterotrophs (consumers, decomposers)
gets nutrients from decaying organisms
Decomposers
one organism benefits from an interaction, while the other organism is not affected
Commensalism
an organism that hunts other organisms and is the top of their food chain
Predators
consumes (eats) other organisms
Consumers
a unstable amount of organisms that the resources in the ecosystem cannot support
Overpopulation
a theoretical perfect world with no limiting factors
