Ecosystem: All living and non-living things interacting in an area.

Community: Different populations living together.

Symbiosis: Close relationship between speciesb (mutualism, parasitism, commensalism).

Predation: One organism kills and eats another.

Carrying capacity: The largest population size an environment can support.

Producers (autotrophs): Make their own food (plants, some bacteria).

• Photoautotrophs: Use sunlight for energy.

• Chemoautotrophs: Use chemical reactions for energy.

Consumers (heterotrophs): Get food from other organisms (herbivores, carnivores, omnivores).

Decomposers (saprotrophs): Break down dead matter and recycle nutrients (fungi, bacteria).
