An ecosystem is a community of living organisms (plants, animals, and microorganisms) interacting with each other and their physical environment.
Think of an ecosystem as a bustling city. Just like how people in a city interact with each other and their surroundings, different organisms in an ecosystem interact with one another and the environment they live in.
Biodiversity: The variety of different species of plants, animals, and microorganisms within an ecosystem.
Trophic Levels: The hierarchical levels in an ecosystem's food chain or food web, representing the flow of energy from one organism to another.
Habitat: The specific place where an organism lives within an ecosystem.
