5.3.4 List Three Factors that set limits to population increase

These factors are limiting factors!

Limiting factors control a process such as population growth. Some examples are
- how much food is available (this really limits how many top predators can live in an area, since they have such scandalous energy intake)
- if there is disease
- amount of predation (predators kill a lot of animals, preventing explosions in population)
- available nesting sites

But those are for animals... what about plants?
- how much light is available?
- whats the temperature?
- how much carbon dioxide?
- how much water?
