Predation




Predation is when one animal eats another.
One species benefits by getting food. The other
species is killed.
Competition is when two organisms are trying
to get the same resources, whether it's food,
water, or sunlight. Neither species benefits
from this relationship,
Examples of predation: Lion-antelope, Beardeer
Examples of competition: Bear-deer, wolf-deer
Predation
Symbiosis



Under Symbiosis there are several types of
relationships. The first is mutalism
Mutualism: Both species benefit. The two
organisms help each other.
Examples: Dandelion-honeybee, Sea anemoneclown fish, Red billed oxpecker-impala, tick
eating birds-hippos
Mutualism
Symbiosis
Commensalism: One species benefits. The other
species is unaffected. A common example is an
animal using a plant for shelter.
Examples: Robin-American Maple, Mites-In
Human Beds, Millipedes-Birds, Barnacle- On
back of Manatee
