    Study Notes

    Ecosystem

    • A system of living and nonliving components that interact within a given area.

    Organism

    • A self-contained living entity.

    Symbiotic Relationship

    • A close association between two different species.

    Mutualism

    • A symbiotic relationship where both organisms benefit.

    Predation

    • A symbiotic relationship where one organism (predator) hunts and kills another organism (prey) for food.

    Parasitism

    • A symbiotic relationship where one organism (parasite) benefits at the expense of another organism (host), causing harm.

    Competition

    • A symbiotic relationship where multiple organisms vie for the same resource.

    Commensalism

    • A symbiotic relationship where one organism benefits, and the other is neither harmed nor benefited.

    Population

    • A group of individuals from the same species residing in a specific area.

    Predator

    • An organism hunting and consuming other animals for energy.

    Prey

    • An organism being hunted and killed by a predator.

    Abiotic Factor

    • A non-living component of an ecosystem.

    Biotic Factor

    • A living component of an ecosystem.

    Resource

    • Any object or substance in the environment required by organisms for growth, maintenance, and reproduction.

    Food Chain

    • A linear model demonstrating the flow of energy from one organism to another.

    Food Web

    • A complex model illustrating the interconnected energy transfer between producers, consumers, and decomposers within overlapping food chains in an ecosystem.

    Herbivore

    • An organism consuming solely producers (plants).

    Carnivore

    • An organism consuming other animals.

    Omnivore

    • An organism consuming both plants and animals.

    Heterotroph

    • An organism obtaining energy from consuming other organisms. Consumers and decomposers are heterotrophs.

    Autotroph

    • An organism capable of producing its own food, also known as a producer.
