Factors that affect the capacity of the ecosystem

  • If the Grey fox population increases, then the Jackrabbits population would decrease because Grey fox prey on them.
  • If the Wrens population decreases then the Gopher snakes population would decrease because that is what they prey on.
  • Disease might spread and animal population decreases

Adaptations of organisms that allow them to survive

  • Cactus Wren is very adaptable to changing environments, as long as native chaparral plants are provided to build its large nests in.
  • The puma is incredibly adaptable to its environment. The preferred prey of the puma is deer, but it will also eat insects, birds and mice.
  • The San Joaquin kit fox is able to adapt to hot temperatures of the chaparral summers and cold temperatures of the winter nights.

Symbiotic relashionships
