What is symbiosis?
Symbiosis- a relationship between two different
species that live on, in or near each other
What are the kinds of symbiosis?
• Commensalism
• Mutualism
• Parasitism
What is commensalism?
Commensalism- a symbiotic relationship in
which one organism benefits and the other is
not affected
Examples of commensalism
Birds

Trees
Birds feed on insects. When cows eat or graze they stir

What is mutualism?
• Mutualism- a symbiotic relationship in which
both organisms are benefited
Examples of mutualism
Bees and Flowers

Nematocysts- a specialized cell containing a barbed or
venomous coiled thread that can be projected in self-defense or to
capture prey.
We are SAFE!!!!!!!!
What is parasitism?
Parasitism- a symbiotic relationship in which the
parasite benefits and the host is harmed
Examples of parasitism
Humans
Mosquitoes

Ticks

What is Competition?
Competition- when organisms compete for
what they need, such as food, shelter/territory,
mate, etc.
Other non-symbiotic relationships
• Competition
• Cooperation
• Predation
Examples of Competition

What is Predation
Predation- when one animal is the predator and
(usually) the smaller weaker animal is the prey
