An Organism’s Niche

  • The unique role of a species within an ecosystem is a

niche

  • An ecosystem is all of the organisms living in an area together with their physical environment
  • It includes their physical home, the environmental factors necessary for survival, and all interactions with other organisms
  • It is different than a habitat (where an organism lives)

Ways in Which Species Interact

  • Interactions are categorized by how one population

interacts with another

  • These interactions depend on whether they harm or help

one another

  • Some interactions are direct, others are indirect
  • This is still being studied to better understand its

complexities

Competition Indirect Competition

  • Some species may never come in contact with each other and still compete
  • (^) Ex. One type of insect during the day and another at night Adaptations
  • Some species reduce competition with each other by adjusting their niche
  • (^) This is called niche restriction

Predation

  • An organism that feeds on another organism
  • (^) The organism that is fed upon is called the prey
  • Ex. Coyote and deer
  • Many species have evolved some mechanisms to avoid or defend against predators
