INTERACTIONS BETWEEN ORGANISMS

TYPES OF INTERACTIONS BETWEEN ORGANISMS

• SYMBIOSIS
• -mutualism
• -commensalism
• -parasitism
• PREY-PREDATOR
• COMPETITION

SYMBIOSIS
-symbiosis happens when two or more organisms of different species live closely together and interact with one another.
Symbiosis includes mutualism,commensalism and parasitism

MUTUALISM
-an interaction that benefits both organisms.

SEA ANEMONE and CLOWN FISH
~The sea anemone protects the clown fish from predators and supplies food to it.
~The clown fish cleans the sea anemone and provides nutrients to the sea anemone in the form of waste

LICHEN
-lichen are algae and fungi that live together.
~The fungi supply water and minerals to the algae.
~The algae carry out photosynthesis and supply food to the fungi

MYNAH and BUFFALO
~The mynah gets food from the buffalo by eating lice that sticks to the body of the buffalo.
~The body of the buffalo is free of lice

COMMENSALISM
~the interaction between two organism which only benefits one organism without harming or benefiting the other
~commersial organism that benefit

REMORA FISH and SHARK

~the remora fish(commensal)latches on the shark(host) and gets its food from scraps scattered by its host.

BIRD'S NEST FERN and
TREE

~The Bird's nest fern(commensal)grow in between the branches of trees (host) to get sunlight.

PARASITISM

-an interaction that benefits one organism only harms the other
*parasite is the organism that benefits.
*host is the organism that is harmed
TAPEWORM
~The tapeworm(parasite) that lives in the human intestine(host) absorbs nutrients.
LICE
~lice(parasite) suck the blood of humans and animals(host)

PREY-PREDATOR
-involves one organism that eat another organism.
-Prey is the organism that is eaten by the predator
-Predator is the organism that hunts another organism for food.

COMPETITION
-competition happens when organisms in one habitat compete for limited supply of basic needs such as light,space,water,food and mates.
