Population can’t go on forever, eventually they will run out of
resources.
Carrying capacity is the largest population that can be
sustained by available resources.
A limiting resource or factor is one in short supply prevents
growth of a population.
Biotic factors are alive: prey, predators, disease
Abiotic factors are nonliving: weather, pollution, pesticides,
temperature, salinity, waves, gravity

These hermit crabs are competing with each other for the best home.
When the same species compete it is intraspecific competition

The whale shark evolved to have a big mouth to better feed on
plankton

Interspecific competition is between species.
Competitive exclusion is when one species eliminates another by
out competing it.
Resource partitioning is how species may share a resource. They
may feed at different times or at different places.
Niche is an organisms role in the ecosystem
