  1. SYMBIOSIS "LIVING TOGETHER"

  2. PARASITISM • One organism is helped or benefited while the other organism is harmed. • Ex.) Tapeworms and roundworms live in the intestines of dogsand cats.

  3. COMMENSALISM • One species benefits and the other species is neither harmed nor benefited. (unaffected) • In a region of Siberia in Russia a peregrine falcon and red-breasted goose have a commensal relationship. During the nesting season the falcon protects the geese from predators. The geese benefit, while the falcon is neither benefited or harmed.

  4. MUTUALISM • Both species benefit! • Mutualism is between a type of ant and a species of acacia tree living in the subtropics.  The ant protects the tree by attacking any herbivore that tries to feed on it. The ants also kill any plant that begins to grow too close to the acacia.  The tree provides nectar and a home for the ants.

  5. Carrying Capacity/Competition • The largest population an environment can support at any given time. • Depends on Food, Water, Living Space, and other resources. • The largest population=carrying capacity!
