Definition - Environment

The surroundings or conditions in which a person, animal, or plant lives or operates. Most commonly used describing the "natural" environment and means the sum of all living and non-living things that surround an organism, or group of organisms. The sum total of all surroundings of a living organism, including natural forces and other living things, which provide conditions for development and growth as well as of danger and damage.

Types of Natural EnvironmentTerrestrial 1. Poles 2. Tundra 3. Taiga 4. Tropical rainforest 5. Grasslands 6. Deserts Aquatic 1. Ponds 2. Lakes 3. Rivers 4. Estuarine 5. Open waters 6. Shorelines rocky, sandy, coralline, mangroves, swamps

Counterparts in Altered Human Ecosystems1.

Material acquisition mining, agricultural growth,domesticated animals

2. Material transformation factories, craft shops etc. 3. Material disposal domestic waste water, garbage 4. Material recycling junk shops, recycling shops,

Question: How efficient do they do it? Time and material

Energy use and transformation in Human altered ecosystems Sunlight fossil fuels combustion electricity Sunlight plants domesticated animals heat Electricity work, heat, cold, light, etc.

Questions What is/are the determining factors in the identity of

an ecosystem? Is it the same for aquatic and terrestrial ecosystem? What are the determinants in a human habitat?

Ecological succession It is a process by which an area is able to

reach its full potential by going through a series f ecological states before reaching its

climax stage.

How do you transform.....Lava that has solidified Tropical rain forest

Ecological Succession:Lichens break down rocks, dies creating a thin soil. 2. Grasses deeper roots and more biomass creates a deeper and richer soil quality. 3. Small trees and shrubs roots reaching bedrock material facilitate more material weathering that adds to soil formation . 4. Large trees and plants more organic biomass , deeper roots sometimes reaching the bedrock Aquatic ecosystems are more determined by physical parameters such as light, turbidity, substratum1.
