What is an Ecosystem?
A biological community of interacting organisms and their physical environment, including both living and nonliving components.
A group of similar organisms that can breed and produce fertile offspring.
A large area characterized by its vegetation, soil, climate, and wildlife.
A process by which plants convert sunlight into energy.
What is a Resource Population?
A population of organisms that serves as a food source for another population in an ecosystem.
A group of organisms that compete for the same resources in an environment.
A population that is endangered and requires conservation efforts.
A collection of organisms that live in the same habitat but do not interact.
Consumer Population
A population of organisms that obtains energy by feeding on a resource population within an ecosystem.
A group of organisms that produce energy through photosynthesis.
A collection of organisms that live in the same habitat but do not interact.
A population of organisms that only consumes non-living resources.
What is a Decomposer?
An organism that breaks down dead organic material, recycling essential nutrients back into the ecosystem.
A type of plant that produces its own food through photosynthesis.
An animal that primarily feeds on living plants and animals.

Protein
An organism that obtains energy and nutrients by feeding on other organisms in an ecosystem.
An organism that produces its own food through photosynthesis.
An organism that decomposes dead matter and recycles nutrients back into the ecosystem.

Stability
The ability of an ecosystem or population to resist change and remain in a relatively constant state over time.
The process by which species evolve and adapt to their environment.
The fluctuation of species populations in response to environmental changes.
The introduction of new species into an ecosystem.
