Competition
Non-Plants
Eating each other so plants can eat them
Eating everybody
Pathogens

Limiting Factors
Available necessary requirements for a plants survival
Clumped
Uniform
Not equally spaced but averaged out eventually
equally spaced / non-clumpy
Division based on age
rule of exponentiation
Uses all available resources immediately to guarantee survival
Live longer than most others to use resources when they are available and survival
Physical size and relation to the environment
Is this actually a word?
Number and diversity of species that live and coexist in an environment
Temporary changes to an ecosystem that could encourage a new species of plant to settle and germinate
Creates a trophic pyramid #
