Study Notes

Carnivore

  • Organisms that primarily consume meat for energy and nutrients.
  • Obtain their diet through predation or scavenging.

Herbivore

  • Animals that exclusively feed on plants.

Omnivore

  • Organisms that eat both plant and animal-based foods.

Producer

  • Autotrophic organisms that create complex organic compounds.
  • Use photosynthesis or chemosynthesis to produce energy from inorganic materials.

Primary Consumer

  • Typically herbivores that directly consume producers (plants).
  • May also include omnivores that feed on both plants and animals.

Secondary Consumer

  • Feed on primary consumers and can be either carnivores or omnivores.
  • Carnivores primarily eat herbivores, while omnivores consume both plants and animals.

Tertiary Consumer

  • Top-level carnivores in the food chain.
  • Exclusively feed on secondary consumers.

Food Chain

  • A linear sequence outlining how energy and nutrients flow through different organisms.
  • Each organism relies on the next as a food source.

Food Web

  • A complex network of interconnected food chains.
  • Demonstrates the interdependence of various organisms in an ecosystem.
