Questions and Answers

What is an abiotic factor?

An abiotic factor is a non-living component that influences an ecosystem.

List four examples of abiotic factors that can affect species distribution.

Temperature, light, water salinity, and soil pH.

How does temperature influence the types of organisms found in a habitat?

Temperature affects the metabolic rates and reproductive cycles of organisms, influencing their survival.

Explain how light availability can impact an ecosystem.

<p>Light availability is crucial for photosynthesis, affecting plant growth and, consequently, the entire food web.</p> Signup and view all the answers

Study Notes

Ecology

  • Ecology is the scientific study of interactions among organisms and their environment.
  • It's an interdisciplinary field incorporating biology and geography.
  • Ecology studies the distribution and abundance of organisms.
  • It examines the interaction between organisms and their environment.
  • Ecology also looks at the structure and function of ecosystems.

Key Vocabulary

  • Biosphere: The parts of Earth where life exists.
  • Ecosystem: A community of organisms and their non-living physical environment interacting with each other.
  • Community: Multiple populations of different species living together in the same habitat.
  • Population: A group of organisms of the same species living in the same area at the same time.
  • Organism: An individual living thing.
  • Habitat: The place where an organism lives.
  • Abiotic factors: Non-living factors affecting an ecosystem (e.g., temperature, light, water).
  • Biotic factors: Living organisms in an ecosystem and their interactions (e.g., competition, predation).

Levels of Biological Organization

  • The biosphere encompasses all ecosystems.
  • An ecosystem is comprised of communities.
  • Communities consist of populations.
  • Populations are groups of organisms of a single species which live in the same place at the same time.
  • Organisms are individual living things.

Abiotic Factors

  • Abiotic factors include water, light, soil type, temperature, wind, and humidity.
  • Abiotic factor determine which kind of organisms can survive in an environment.

Biotic Factors

  • Biotic factors are interactions among living things.
  • Competition between species for resources (interspeicific)
  • Competition between individuals of the same species (intraspecific).
  • Feeding relationships among organisms (e.g. predator-prey relationships).

Limiting Factors

  • Limiting factors affect the survival and distribution of organisms.
  • These factors can be abiotic or biotic.

Other important concepts

  • Adaptation aids organisms to survive in their environments.
  • Migration is the movement of animals from one place to another seasonally.
  • Animals migrate usually for better food sources or suitable breeding grounds.
  • Coral reefs exist in warm ocean waters.
