Animals Multi-cellular organisms that cannot make their own food, but have to ingest other organisms Do not have a cell wall but a skeletal structure.

Symbiotic Relationships

How Do We Relate?. Relationships Many organisms have developed a close relationship with other organisms of different species. These close relationships.

It’s all about relationships! Symbiosis It’s all about relationships!

Symbiosis is a close relationship between two or more different species.

Mutualism—A relationship where both species benefit from the relationship. 50/50

Mutualism

Parasitism-- A relationship between two species in which one species (the parasite) gets energy by the disabling the other species (the host) 100/0

Parasitism Host- Organism that is being used by the parasite as a habitat (place to feed). Can become seriously ill or die. Parasite- Organism that is benefiting by getting nutrients. Can live inside or be outside of host

Commensalism—A relationship where one species obtains food or shelter from the other species. Does not harm or help the other species.

Example- Tiny mites living on human eyebrows Commensalism Example- Tiny mites living on human eyebrows

Predation: When one organism hunts, stalks another (the prey) resulting in eating, killing, or injuring it.

Predator Organism that hunts, kills, eats and stalks another organism Prey- Organism that is killed, hunted, stalked or eaten by a predator

Competition

When two organisms use physical (direct) or non-physical (indirect) means to obtain the same thing.. For food, mates, shelter, followers, etc.

2 Types Direct: Kevin gets into a physical altercation (fight) with Justin regarding him dating Nikki. Indirect: Nikki is dating Justing and he is aware that she is seeing Kevin. Justin then vows to win her over by lavishing her with gifts and flower. However, he never sees Kevin.
