- Ex. Amazon rainforest home to more than 200 species of hummingbirds, Ontario only has a single species.
- `Population`: A group of organisms of one species that interbreed and live in the same place and time.
- Population often change due to both **natural and artifical** factors (human activity).
- `Carry Capcity`: The maximum population size of a **particular species** that a given ecosystem can sustain.
- `Carry Capacity`: The maximum population size of a **particular species** that a given ecosystem can sustain.
- `Pollution`: harmful comtaminants released into the enviornment.
- `Bioremediation`: the use of micro-organisms to consume and break down environmental pollutants.
- `Photosynthesis`: The process in which the Sun’s energy (LIGHT) is converted (put together with) into chemical energy AS GLUCOSE (sugar).

- `Monocultures`: cultivation of a single crop in an area.
- Bad, bees can't pollinate, as there is only one crop, destruction of one crop will result in total food shortage from that crop, as we are only growing one crop. Also nutrient cycling is disrupted and less crops can be grown at the same rate.
- `Pest`: Any plant, animal, or other organism that causes illness, harm, or annoyance to humans.
- `Interspecific`: 2 species fighting.
- `Intraspecifict`: Same species fighting.
- `Interspecific`: Different species fighting.
- `Intraspecific`: Same species fighting.
- `Watershed`: An area or ridge of land that separates waters flowing to different rivers, basins, or seas.
- `Intertidal Zone`: The intertidal zone, also known as the foreshore and seashore, is the area that is above water at low tide and underwater at high tide.
- `Limiting Factor`: Any factor that restricts the size of a population.

### Cellular Respiration
- Process of converting sugar into carbon dioxide, water and energy
- Makes stored energy available for use, Takes place in the mitochondria
- C<sub>6</sub>H<sub>12</sub>O<sub>6</sub> + 6O<sub>2</sub> = 6CO<sub>2</sub> + 6H<sub>2</sub>O + energy.
1. Original energy stored in the sugar is released
2. Occurs continuously
3. Does NOT require light energy

- Food are a series of steps in which organisms transfers energy by eating or eaten (pg. 43).
- Food webs show the complex interactions within an ecosystem (pg. 44).
- Each step in a food chain or web is called a `trophic` level. Producers make up the first step, consumers make up the higher levels. E.g. first trophic level are producers, second trophic level are primary consumers, etc.
- Detrivores + scavengers are off to side (with all arrows pointing on it.
- Detrivores + scavengers are off to side (with all arrows pointing on it).
- **First Trophic Level**: `Plants`.
- `10% rule`, Only 10% of energy is stored in each organism, 90% of energy is lost (heat consumption).
