1. Population growth rate is the rate or speed at which a population grows.
1.1. Exponential growth- is growth of a population, normally avoiding its limiting factors, that multiplies over time.(creating a J-curve graph) On the other hand a S-curve graph is made by a population that is very effected by its limiting factors; these populations grow to their carring capacity then begin to die off from limiting factors
2. Trophic Levels
2.1. Tertiary comsumer
2.2. Secondary consumer
2.3. Primary consumer
2.4. Producer
2.4.1. Decomposer
3. Biodiversity- the variety of organisms and their differences around the world.
4. Ecological succession-growth of populations
4.1. Climax community- a communtiy with a max number of organisms
4.2. Primary succession- the first time life/populations grows in an area
4.3. Secondary succession- the times when life/population grow back in a area
4.3.1. Pioneer species- the first organisms/populaton to show up in an lifeless area
5. New node
6. A Food Chain is a diagram showing the transfer of energy in a continues and repeating line.
7. A Food Web shows all energy transfer relationships in an enviroment/ecosystem.
8. Ecological succession
8.1. Secondary succession- When an ecosystem is damaged or destroyed and the local community starts to grow again
8.1.1. Pioneer species- an organism that can thrive in an area with limited resources. Usually the first organisms to move a new enviroment.
8.2. Primary succession- the first time an community of wildlife grows up in an area
8.3. Climax community- a community in which populations have a max number of organisms.
8.3.1. Limiting factors-are biotic and abiotic things that limit the max population size.
8.3.1.1. Carrying capacity- is the max sized community that a specific enviroment can contain. Once the carrying capacity is reached limiting factors down size the populations.

12.5.1. Water pollution
12.5.1.1. Aquifer- under ground water sources
12.6. Marine biome
12.6.1. Watershed- a area of land and water which contributes pollution to a water source
12.6.1.1. Impermeable surfaces- roof,side walk,road,parking lot, etc.
12.6.1.1.1. Stormwater runoff
12.6.1.2. point source- pollution from a known source which can be traced back to its source
12.6.1.3. nonpoint source- collective pollution from an unknown source
