ecosystems

• Population:

  all the individuals of one species in a particular area
• Community:

  All the interactions of all the living organisms in a particular area
• A stable community is one where all the species and environmental factors are in balance so that population sizes remain fairly constant.

  A population refers to all the organisms of one species found in a particular area.

  Whereas a community is all the populations of different organisms living together in a habitat
• interspecific competition - Competition between different species trying to occupy the same niche.
• 1. Predator eats prey so prey decreases.
  2. Fewer prey means there is a greater competition between the predators for resources.
  3. Predator population decreases as some cannot eat enough prey.
  4. Fewer predators means prey numbers increase.
  5. More prey = more predators.
