competition + interdependence

• In 'ecology', it is important to know that all organisms have relationships.

  • Therefore, if something changes, it can affect other parts of an ecosystem.

  Such as predators not having enough to eat because the population of mice has declined.
• A habitat is the place where an organism lives.
• The 'population' is all of the organisms of a particular species that live in a habitat.
• The 'community' is all the populations of different species that live together in a habitat.
• Biotic factors are the living factors of an environment.

  • For example, the number of predators.
• Abiotic factors are the non-living factors of an environment.

  • For example, temperature and soil pH.
• An 'ecosystem' is the interaction of a community of living organisms with the non-living parts of their environment.
• Organisms have to compete with each other in order to get enough resources (such as food, territory and mates).

  • This competition may be with the same species or different species.
• Interdependence is the idea that all species depend on other species in some way.

  
• Plants compete for;

  • Water
  • Mineral ions
  • Light
  • Space
