    Study Notes

    Ecosystem and Community

    • An ecosystem is a community of living and non-living components interacting with each other in a specific environment.

    Interdependence in a Community

    • Interdependence in a community refers to the mutual reliance and interactions between different species, including plants, animals, and microorganisms, within an ecosystem.

    Resource Competition

    • Plants in an ecosystem compete for essential resources such as light, water, nutrients, and space.

    Community in Ecology

    • A community in ecology refers to a group of different species living and interacting with each other in a specific area or habitat.

    Species-Habitat Relationship

    • The relationship between a species and its habitat is one of interdependence, where the species adapts to the habitat and the habitat, in turn, supports the survival and growth of the species.
