6. Factors in a ecosystem
6.1. Biotic Factors
6.1.1. Anything in a ecosytem that is living, was living, or part of a living thing.
6.2. Abiotic Factors
6.2.1. Anything in a ecosystem that never lived or never will live.
7. Carrying Capacity
7.1. The total population that a ecosystem can carry before the population needs to be reduced.
7.1.1. Limiting Factors
7.1.1.1. Factors that limit the population of a certain area so that it does not reach the carrying capacity.
8. Population Growth
8.1. Population growth rate
8.1.1. J-Curve
8.1.1.1. When the population continues to grow without stopping. The curve stays steady before jumping up showing a population spike.
8.1.2. S-Curve
8.1.2.1. When the population grows till it hits its carrying capacity. The curve shows this by slowly growing and then hitting a populaiton spike before leveling out.

10.2.1. Resources that the earth cannot replace in a human lifespan. Examples are diamonds, gold, and uranium.
11. Pollution
11.1. Nonpoint source
11.1.1. Anything laying on the ground that ends up in water. Can only be stopped if people are more wise about what they use.
11.2. Point Source
