Study Notes
Forest Characteristics
- Forests are complex, dynamic entities, made up of living organisms (biotic community)
- Forests are characterized by various layers of vegetation, including the topmost layer and understorey
- Human activities, such as deforestation, can damage forests
- Forests provide essential resources and services for supporting life
Forest Dynamics
- Forests are dynamic systems, constantly changing over time.
- Plants and animals depend on each other for survival (interdependence).
- Decomposition of dead plants and animals is crucial for nutrient cycling within the forest ecosystem
- Environmental factors, such as temperature and rainfall, influence the types of plants and animals that thrive in a forest
Importance of Forests
- Forests are vital for humans and other creatures
- Forests provide numerous uses, including various products and resources
- Forests play a crucial role in maintaining ecological balance and biodiversity
- Forests help sustain human well-being.
Forest Components
- A forest can be described as an entity with many components
- The topmost layer of the understorey can include dead leaves, branches, and other organic matter
- Examples of decomposers include bacteria and fungi
- Human activities such as deforestation and pollution can significantly damage forests.
Food Webs in Forests
- A food web is a complex network of interconnected food chains
- A forest food web involves many interacting biotic species
- The total food items and available nutrients in a region fluctuate
- The nutrients in soil may increase or decrease depending on factors such as conditions caused by natural events or human activities.
- Different food chains of a region involve diverse interactions among organisms
