Ecosystem Interactions and Components

Ecosystems consist of living (biotic) and non-living (abiotic) components. Biotic factors include organisms like polar bears and mosses, while abiotic factors include elements like rocks and water. Organisms interact with both living and non-living components, such as a caterpillar with a leaf or a fox with a plant. These interactions form the basis of ecosystems.
