Species Interactions
The effects organisms in a community have
on one another

Types of species interactions
• Predation
• Mutualism
• Competition
• Commensalism

How do species interactions affect the two species involved?

Predation
• When an animal eats another animal or plant
– Carnivores
– Herbivores
– Parasites

Carnivores• Animals that only eat other animals
![Page 6: Species Interactions The effects organisms in a community have on one another](https://reader036.vdocument.in/reader036/viewer/2022062423/5697c01f1a28abf838cd19a1/html5/thumbnails/6.jpg)
Herbivores• Animals that only eat plants
![Page 7: Species Interactions The effects organisms in a community have on one another](https://reader036.vdocument.in/reader036/viewer/2022062423/5697c01f1a28abf838cd19a1/html5/thumbnails/7.jpg)
Parasites• An animal or plant that
eats the tissues of another plant or animal without killing it
• The animal the parasite eats is called a host

Mutualism
• When two animals or plants interact in a way that helps both of them

Symbiosis
• A type of mutualism where two organism depend on each other to survive
![Page 11: Species Interactions The effects organisms in a community have on one another](https://reader036.vdocument.in/reader036/viewer/2022062423/5697c01f1a28abf838cd19a1/html5/thumbnails/11.jpg)
Competition
• When two animals or plants compete for resources, hurting both of their chances for survival
![Page 12: Species Interactions The effects organisms in a community have on one another](https://reader036.vdocument.in/reader036/viewer/2022062423/5697c01f1a28abf838cd19a1/html5/thumbnails/12.jpg)

Commensalism
• When one animal or plant uses another animal or plant to help it survive, but does not affect the other animal in any way
![Page 15: Species Interactions The effects organisms in a community have on one another](https://reader036.vdocument.in/reader036/viewer/2022062423/5697c01f1a28abf838cd19a1/html5/thumbnails/15.jpg)
Detritivores and Decomposers
• Plants, animals and fungi that eat and decompose dead things and poop

In your groups . . .
• You must have at least one parasite, • one herbivore, and • One carnivore
