  1. Ecological Interactions

  2. Interacting with the Environment LIMITING FACTORS • An environment only contains a certain amount of food, water, shelter and other resources. • When one of those resources becomes scarce it is called a LIMITING FACTOR. • This means that a population’s size can become limited by that factor.

  3. Interacting with the Environment CARRYING CAPACITY • When limiting factors become scarce populations become smaller. • This means that an environment has reached carrying capacity. • CARRYING CAPACITY is the maximum number of organisms that an environment can support.

  4. Interactions Between Organisms COMPETITION • Competition happens between populations. • Competition also happens within populations.

  5. Interactions Between Organisms Predator/Prey Interactions • Predators have adaptations that make them efficient hunters. • Ex: Speed, stealth, coloration • Prey have adaptations that help them escape from predators. • Ex: Traveling in packs, warning coloration, mimicry, chemicals

  6. Interactions Between Organisms SYMBIOSIS • Mutualism – Both organisms benefit. • Commensalism – One organism benefits the other is unaffected. • Parasitism – One organism benefits and the other is harmed.

  7. Interactions Between Organisms Coevolution • When a long-term change takes place in two species because of their close interactions with one another, the change is called COEVOLUTION.
