Study Notes
Ecosystem Operations
- The operation of an ecosystem involves the production, growth, and death of living components, and these processes also influence the abiotic aspects of the habitat.
- Transportation within an ecosystem can be achieved by factors such as wind, water, and gravity.
Soil Formation
- Soil is formed from the outer layer of Earth's crust.
- Residual soil has the same chemical composition as the original rocks from which it forms.
- Transported soil does not have the same chemical composition as the original rocks because it has been moved and altered.
Soil Formation Processes
- There are two main processes of soil formation:
- Bedrock zone (horizon D): This layer is composed of the original rocks.
Water Content of Soil
- Water is essential for living organisms as it is a major constituent of biological processes such as germination and cell structure.
-
Soil-water is classified into four types:
- (Types of soil water will need to be provided from the source material for the study notes to be complete).
Soil Erosion
- Erosion is the gradual removal of the outer layer of soil by strong winds.
- Erosion exposes roots to environmental factors, such as light, leading to root death.
- Soil is a source of organic matter for plants, and the percentage of organic matter increases with denser vegetation.
- Forests have the highest levels of organic matter due to the abundance of plant remains.
