Abiotic |
Abiotic (Non-living) Factors: physical and chemical components that effect the environment. e.g. Availability of water (rainfall), temperature, amount of sunlight. |
|
Biotic |
Biotic (Living) Factors: All the living organisms. Their numbers, distribution and interactions. |
|
Biome |
A group of ecosystems around the world with similar abiotic factors. e.g deserts around the world. |
|
Terrestrial (Land) |
35% of the earth is covered by terrestrial environments. Main factors are the availability of water climate. Terrestrial Biomes: rainforest, deserts, grasslands and arctic tundra. |
|
Aquatic (Marine/Freshwater) |
65% of the earth is covered by aquatic environments. Main factors: availability of dissolved oxygen, amount of sunlight. Biomes: open seas, estuaries rivers and ponds. |
