Types of Interactions

• Habitat: A place where organisms live
• Population: Organisms of the same species/kind that live in a particular habitat
• Community: Made up of the different plant and animal populations living together and interacting with each other in a habitat
• Ecosystem: The interactions between a community and it’s physical environment
• (Optional) Ecology: The study of ecosystems
• (Optional) Ecologist: A person who studies ecology
• Abiotic factors: Physical/non-living factors that affect the environment.

  Abiotic factors:

  • Light
  • Temperature
  • Water
  • Air
  • Minerals
  • pH level
• Biotic factors: The living organisms in a habitat, such as plants, animals, and microorganisms.
• The abiotic factors in the environment determine the type of biotic factors that can live in the environment. Biotic factors that cannot adapt to the abiotic factors, will not survive in that environment
• Adaptations are the physical or behavioral characteristics developed over time to help organisms survive better in their own environment. Adaptations can be structural or behavioural
• Types of interrelationships in an ecosystem:

  • Predator-prey 😋-🍖
  • Mutualism 😄-😄
  • Parasitism 😄-😥
  • Commensalism 😄-🫤
• Organisms in a habitat cannot survive alone. They interact with each other for example, by eating them, by competing with them for food, water and light, or by providing them with shelter and protection. The fate of one organism will affect the survival of other organisms in the environment. Changes in environmental conditions or removal of any organism disrupts the stability of an ecosystem.
