Photosynthesis |
-Carbon dioxide+Water⇨ Sugar and Oxygen -The process in which the Sun’s energy is converted into chemical energy |
|
|
Cellular Respiration |
-Sugar+Oxygen⇨Carbon dioxide+Water -The process by which sugar and oxygen are converted into carbon dioxide |
|
|
Carbon Cycle |
Adding carbon to atmosphere -cellular respiration -deforestation -burning fossil fuels -weathering of rocks Removing carbon from atmosphere -photosynthesis -formation of rocks and fossil fuels -dissolving into water |
|
|
Nitrogen |
Nitrification -The process of turning nitrogen out of the atmosphere and converting it into nitrates. Specialized bacteria Denitrification -Nitrates turning back to nitrogen |
|
|
Predator-prey relationships |
-Predator population follows prey relationship -Every time predator population goes up, prey relationship goes down |
|
|
Bioamplification |
Pesticides/chemicals stay in food web in small amounts. The concentration of the chain increases as it goes up the food chain. The small non harmful amounts of chemical become large concentrated amount dangerous for top predators. |
|
|
Disruption in matter cycles |
Carbon cycle- We add excessive amounts of carbon dioxide into the carbon cycle Nitrogen cycle- We add chemical fertilizers to our soil. Chemicals and extra nitrate can get into ponds causing an algae |
|
|
Biotic factor- |
a factor of an ecosystem that was living or was living |
|
|
Abiotic factor- |
a factor of an ecosystem that is non-living. Example: Water |
|
|
Producer- |
an organism that is able to produce their own energy, serves are the source of food for consumers |
|
|
Consumer- |
an organism that must consume other organism to obtain energy |
|
|
Limiting factors |
A condition that places an upper limit on the size of population. Factors can be biotic or abiotic, dependent of population or independent Biotic- Interactions between individuals: competition, predation etc. Abiotic- availability of water, light, temperatures, acidity of water, salinity of water etc. Dependent: dependent on population size (ex: Disease) Independent: independent on population size (ex: forest fire) |
|
|
Law of tolerance- |
the tolerance range of each species, determines where species can live |
|
|
Biodiversity- |
the variety of life found in an area |
|
|
Threats to biodiversity |
-Overexploitation -Deforestation -Urban/agriculture expansion -Pollution -Climate Change |
|
|
Ecological succession- |
the gradual predictable changes in an ecosystem following a disturbance |
