(+)(0)
Commensalism
Example of mutualism
Followers and pollinators
Example of competition
Baby birds competing for same food
Example of commensalism
Birds in nest
Reduces population size since there are fewer resources available
Competition
How can competition lead to resource partitioning
Different species use the same resources in different ways to reduce competition
Ex: Temporal, spatial, morphological
Intraspecific
Between the same species
interspecific
Between different species
More plant and animal life in an ecosystem
Biodiversity
An area that shares a combination of average yearly temperature and precipitation
Biome
