Species Interact In
Biological Communities
By: Jennifer and Gabe
Compititon Between Species
• interspecific competition: the competiton between
species for food and other resources.
• Compeition Exclusion: one species succeeding over
another when the growth of both species is limited
by the same resource
• members of a population compete for a limited
amount of resources.
Causes and Results of Inspecific
Competition
Causes:
1.Limited amount of
resources
Results:
1.Alot more competition
or animals
move/migrate.
2.Limited amount of
(any food such as grass)
2. It puts the organisms
out of balance because
• the animals that eats
grass dies
• then the animal that
eats the insect that
died, dies

Competition
Article On Interspecific Population
Rabbits that were put on Austrialia:
1.Ate all of the grass
2.Since they have no natural predator there, they are
becoming over populated
3.This also shows interspecific competition

Adaptions of Predator and Prey
Predator:
• Keep competing
populations down
• Some also have colors
that camoflague them
so they can't be seen
• Some have acute
sense that help them
find prey
Prey:
• Use camoflague,
warning coloring, and
mimicry
• Others also retreat into
safe locations
• Other things (such as
plants) have poisonous
chemicals
What is a Symbiotic
relationship?
A Symbiotic relationship is a close
ecological relationship between two or
more different species.
Types of symbiotic relationship
Symbiotic Relationship Terms:
-Mutualism:Both species benefit.
-Commensalism: One species benefits and
the other is unaffected.
-Parasitism: One is benefited and the other
is harmed.
-Competition: Neither species benefits.
-Neutralism: Both species are unaffected
The Clownfish and the Anemone
show Mutualism
These two speceies have a Mutually Benefical
symbiotic relationship.
Clownfish have a protective skin thus they aren't
harmed by the anemone.
Barnacles living on whales
shows Commensalism
-Barnacles are arthropods. The whale acts as
a rocky surface for the Barnacle to fix itself to.
-The Barnacle gains acces to Nutrient-rich
waters. The whale is not harmed.
Parasitism
Also called a parasitic relationship; one benefits and
the other is harmed.
A parasite is what harms the host.
They can be inside or on the surface of the host.
Paracites rely on the host to survuve.
Koi Paracite- Feed on the Japenese
Koi Fish. They attach to the outter
layer of skin.
Neutralism
Meaning two organisims interact but neither are
affected.
True neutralism is very rare or nonexistent.
It's usually found in situations that are remote or
unimportant.
The Tarantula and the cactus in deserts is an
example.
