Questions and Answers

What is the main focus of the text?

  • The geological features of ecosystems
  • The individual organisms within a species
  • The abiotic part of an ecosystem
  • The biotic part of an ecosystem involving interactions between populations of different species (correct)

    • Which type of community interaction involves one species consuming another species for food?

  • Symbiosis
  • Competition
  • Mutualism
  • Predation (correct)

    • Intraspecific competition occurs between:

  • Members of the same species competing for resources in the same area (correct)
  • Members of different ecosystems striving for survival
  • Members of different species competing for resources
  • Members of different populations collaborating for mutual benefit

    Study Notes

    Community Ecology

    • Community interaction involves different species living in the same area, influencing each other's survival and reproduction.

    Types of Community Interactions

    • Predation involves one species consuming another species for food.

    Intraspecific Competition

    • Occurs between individuals of the same species, competing for limited resources such as food, water, and mates.

    Community Dynamics

    • Refers to the changes in species composition, structure, and function over time in a biological community.

    Keystone Species

    • Characterized as a species that has a disproportionate impact on its environment and plays a crucial role in maintaining the structure and function of its ecosystem.

    Primary Succession

    • The process of ecosystem development on new, uninhabited land, such as after a volcanic eruption or glacial retreat.

    Biological Community vs. Ecological System

    • A biological community refers to the interacting species in a specific area, while an ecological system includes both the community and its physical environment.

    Natural Resources and Species Composition

    • Natural resources can impact the species composition, structure, and function of a community by influencing the availability of resources such as light, water, and nutrients.

    Importance of Community Interactions

    • Community interactions are crucial for maintaining ecosystem balance, as they influence the survival and reproduction of species, and can favor or eliminate biological species.
