 Autotroph  Heterotroph  Herbivore  Carnivore  Omnivore  Scavenger  Symbiosis  Mutualism  Parasitism  Commensalism  Competition  Predation  Predator  Prey

 Nutritional Relationships  Other Animal Interactions  Symbiotic Relationships

Autotroph Heterotroph  Auto- means “self”  -troph means “feeder”  So, an autotroph is an organism that makes its own food  Hetero- means “other”  -troph means “feeder”  So, a heterotroph is an organism that cannot make its own food Grasses & flowers are autotrophs A horse is a heterotroph

Herbivores Scavengers Omnivores Carnivores

 A heterotroph that eats only plants  A heterotroph that eats only animals

 A heterotroph that eats both plants and animals  A carnivore that eats only already-dead animals

Symbiosis – a close relationship between two organisms of different species that benefits at least one of the organisms 1 Mutualism 2 Parasitism 3 Commensalism

A close relationship between organisms of two species in which both organisms benefit The sea anemone and the clown fish have a mutualistic relationship. This means they both benefit. The clown fish benefits because it gets a habitat that is very safe from other predators. The sea anemone (the plant) benefits because the clown fish’s movement allows more seawater in, which allows it to eat more.

A close relationship between organisms of two species in which one organism lives on or in a host and harms it The dog and tick have a parasitic relationship. The tick is the parasite, which is the organism that benefits. It gets a free meals and place to live. The dog is the host, which is the organism where a parasite lives. The dog is harmed and can get very sick.

A close relationship between organisms of two species in which one species benefits and the other is not helped or harmed The whale and the barnacles show commensalism. The barnacles benefit because they get much more sea water access, which gives them more food. They also get a free place to live. The whale is not helped or hurt by the barnacles.

 The struggle between organisms to survive as they attempt to use the same limited resource  An interaction in which one organism kills another for food CompetitionPredation

Predator Prey  The organism that does the killing in a predation interaction  The organism that is killed and eaten by another organism
