Study Notes

Ecosystems

  • An ecosystem: community of living organisms and the nonliving components.

  • Producers: autotrophs, making their own food (e.g., plants).

  • Consumers: heterotrophs, obtaining energy by consuming others (e.g., herbivores, carnivores, omnivores, scavengers).

  • Decomposers: heterotrophs that break down dead organic matter (e.g., bacteria, fungi).

  • Producers: autotrophic organisms that contain chlorophyll and make their own food through photosynthesis using sunlight.

  • Consumers: organisms that get their energy by eating other organisms.

  • Herbivores: eat plants.

  • Carnivores: eat animals.

  • Omnivores: eat both plants and animals.

  • Scavengers: consume dead organisms.

  • Herbivores: feed on vegetation or primary consumers within an ecosystem.

  • Carnivores: prey on other animals, possibly secondary consumers or tertiary consumers.

  • Omnivores: feed on both plants and other consumers.

  • Scavengers: feed on dead animals or plant matter.

  • A food chain: linear sequence of organisms where each organism feeds on the one below.

  • A food web: multiple food chains interconnect.

  • A food web :shows feeding relationships among different organisms.

  • An ecological pyramid: graphical representation of trophic levels.

  • Symbiosis: close relationship between two different species.

    a. Mutualism: Both species benefit.

    b. Commensalism: One species benefits, the other is unaffected.

    c. Parasitism: One species benefits, the other is harmed.

  • Non-Symbiotic relationships: ecological interactions where organisms live apart from one another..

  • Competition: ecological interaction between two or more organisms needing the same resource.

  • Predation: ecological interaction where one organism (predator) feeds on another (prey.)

  • Global Warming: increasing average temperature of Earth's atmosphere.
