intraspecific competition

mimicry
similarity of one species to another that can benefit both
batesian mimicry
example: non venomous snake looks like a venomous one
mullerian mimicry
example: two venomous stuff look like each other
endangered species
in danger of extinction
habitat vs niche
niche= behavior/ trophic levels/where organism belongs in the ecosystem habitat= where it lives
niche partitioning
2 competing species utilize diff resources to avoid competition. (so their not in the same niche)
ecological equivalents
species that occupy the same niches but not in the same region so they don’t have to compete
predation
where 1 organism captures/ kills/ eats another
