Abiotic Features |
Temperature, pH, pressure, light intensity/avalibility, salinity, avalibility of ions and gasses |
|
|
|
Distribution |
Where a species is found and factors which affect this. Transects are used to measure distribution. |
Where |
|
|
Abundance |
Determines how many members of a species live throughout an ecosystem. Quadrants and mark-release-recapture measure abundance. |
How many |
|
|
Photosynthesis Formula |
Carbon dioxide + water → glucose + oxygen 6CO2 + 6H2O → C6H12O6 + 6O2 |
|
|
|
Role of Photosynthesis |
Initial pathway by which energy enters ecosystems. Autotrophs harness energy from the sun and convert it to glucose to be used by other orgainisms. Provides oxygen for respiration of all living things and recycles carbon dioxide. |

|
|
Respiration Formula |
Oxygen + glucose → carbon dioxide + water + energy (ATP) 6O2 + C6H12O6 → 6CO2 + 6H2O + ATP |
Opposite of photosynthesis + ATP |
|
|
Role of Respiration |
Converts glucose into a form of energy that can be used for all functions of the cell. Takes place in the mitochondria. |
|
|
|
Plant Energy Use |
Repair, maintenance, fluid movement and transport, specialised cell functions |
4 points |
|
|
Animal Energy Use |
Fuel chemical rections of cells, much lost as heat |
1, -1 points |
|
|
Aerobic Respiration |
3 stages at which ATP is released, a chain of biochemical reactions, 36 ATP per glucose molecule |

Predator Prey Relationships |
Feeding relationship in which one orgainism obtains food by killing another. Abundance of predator mirrors prey. |
2 points |
|
|
Allelopathy |
Production of allelochemicals by a plant which influence the growth and development of surrounding plants. |

|
|
Symbiotic Interactions |
Two orgainisms that live in a close relationship that benefits at least one of them. |
Broad definition |
|
|
Parasitism |
A relationship in which one orgainism benefits and the other is harmed. Tapeworm parasitism of human. |
Definition + example |
|
|
Mutualism |
Both species benefit from the association. Monkey eats parasites from Ox. |
Defenition + example |
|
|
Commensalism |
One species benefits and the other is unaffected. Epifites grow on plants and derives nutrients from debris of plant and air. |
Definition + example |
|
|
Decomposers |
Use the energy of dead orgaimisns for food, breaking it down into materials which may be reused by other orgainisms. |
Definition |
|
|
Degraders |
Feed on dead orgaimisms and organic wastes of an ecosystem. Scavengers, detrivores, decomposers. |

List |
|
|
Adaptations |
Characteristic which increases an orgainisms chance of survival and reproduction relative to orgainisms which lack this characteristic. Structural, physiological, behavioural. |
