Competition

I can describe resources that organisms have to compete for and explain how adaptations can be helpful.

Lesson details

Key learning points

  1. All living organisms need resources from their habitat to enable them to survive.
  2. Resources are limited, so individuals are in competition for them.
  3. Organisms compete for resources such as food, water, space, shelter, light, mates, pollinators and seed dispersers.
  4. Variation means some individuals are better adapted to compete more successfully than others.
  5. These individuals have the best ‘fit’ to their environment.

Common misconception

Many learners think that the only way animals compete for resources is through physical aggression.

This lessons contains many examples of how animals and other organisms compete for resources.

Keywords

  • Competition - Living organisms struggle for access to limited resources. This struggle is known as competition.

  • Variation - Differences between organisms of the same species are known as variation.

  • Adaptation - An adaptation is a feature that helps an organism to function and survive.

  • Advantage - A feature that helps an organism to compete more effectively in its habitat gives the organism an advantage in the competition.

  • Fittest - Organisms that are the best adapted to their environment are said to be the fittest.

The best adapted organisms don't always survive and reproduce. Random events mean often less adapted organisms survive and reproduce. It's best to use phrases like "increases the chances of survival" than to speak in definite terms.
