Study Notes
Forest Ecosystem
- A forest is a large area of land dominated by trees and other woody vegetation, often with a closed canopy and a complex habitat for various species of plants and animals.
Ecosystem Role
- The primary role of a forest in the ecosystem is to provide habitat and food for a diverse range of plant and animal species, as well as to regulate the climate, conserve soil, and filter water.
Human Impact
- The main threat to forests from human activities is deforestation and land-use changes, mainly for agriculture, urbanization, and logging, leading to widespread habitat destruction and loss of biodiversity.
Tree Growth
- The factor most critical for the growth of trees in a forest is adequate access to water, as it enables trees to perform photosynthesis and facilitates the transport of nutrients and minerals throughout the tree.
