Study Notes

Types of Organisms

  • Herbivore: Exclusively consumes plants.
  • Carnivore: Primarily feeds on other animals; may include some plants.
  • Omnivore: Consumes both plants and animals, exhibiting dietary flexibility.

Ecological Concepts

  • Food Chain: Sequential series illustrating how energy is transferred through consumption, starting from producers to various levels of consumers.
  • Food Web: A complex network depicting several interlinked food chains within a community, showcasing the diverse feeding relationships among organisms.

Predator-Prey Dynamics

  • Prey: An organism that is hunted and consumed by another organism.
  • Predator: An organism that actively hunts and feeds on other organisms for sustenance.

Symbiotic Relationships

  • Symbiosis: Refers to the close interrelationship between two different species that provides benefits to at least one party.
  • Mutualism: A type of symbiotic relationship where both species involved gain benefits.
  • Commensalism: A relationship where one organism benefits while the other is neither helped nor harmed.
  • Parasitism: A harmful relationship where one organism lives on or in a host, causing detriment to the host organism.

Evolution and Interaction

  • Coevolution: The process wherein two interacting species reciprocally influence each other’s evolution, often leading to specialized adaptations.

Nutritional Roles

  • Producer: A self-sustaining organism that generates its own food through processes like photosynthesis.
  • Consumer: Individuals or households that buy goods or services, broadly relating to the idea of consumption in ecological terms.
