- - - - How it responds to resources available, to predators, to competitors
        
        symbiosis - wo species live together which can include parasitism, mutualism, and commensalism
        
        commensalism – one species receives a benefit from another species which enhances fitness of one species; no effect on fitness of the other species.

        competition - the relationship between species that attempt to use the same limited resource (e.g. hyenas fighting with lions over a carcass or trees competing for sunlight at the top of the canopy)
        
        disease - a particular abnormal condition, a disorder of a structure or function, that affects part or all of an organism. includes organisms such as viruses, bacteria, fungi and parasites that cause disease.
        
        mutualism - A type of symbiotic relationship in which both species benefit from the relationship.
        
        parasitism - The host provides a habitat and food for the bacteria, but in return, the bacteria cause disease in the host. This is an example of parasitism or an association between two different species where the symbiont benefits and the host is harmed. Not all parasites have to cause disease.
        
        herbivory - the act of eating plants and a herbivore is an animal that eats plants. Herbivores play an important role in the ecology of any area, influencing plant communities and individual plant growth. A form of predation.
        
        predation - one species feeds on another which enhances fitness of predator but reduces fitness of prey. Herbivory is a form of predation.
  - - - soil temperature
      - air temperature
      - wind speed
      - sunlight intensity
      - soil nutrients
      - water
      - pH
  - - - how the number of individuals in a population changes over time
    - - increase available resources
      - reduce competition
      - reduce pressure from predators
      - introduce animals to new areas
    - - change environment, cause habitat disruption
      - change the biological environment by introducing new species
      - cause secondary extinctions
