COOPERATIVE
INTERRELATOINSHIPS IN
MISSOURI FORESTS
ECOSYSTEM
All the organisms and the non-living
environment within a defined area
DESERT
LAKE
COMMUNITY
Consists of all the interacting animal
populations within an ecosystem.
FOOD WEB
MANY DIFFERENT
COMMUNITIES EXIST IN A
SINGLE FOREST
SYMBIOSIS
Two species living together in close
association over an extended time.
Also called “symbiotic relationships”
3 TYPES OF SYMBIOSIS
1. PARISITISM
2. COMMENSALISM
3. MUTUALISM
PARISITISM
A symbiotic relationship where the
organism lives in or on their host and
does harm to their general well being,
sometimes parasites are fatal.
The parasite benefits, the host does
not.
ONE EXAMPLE OF PARISITISM
Ticks on a deer.
LEECHES
COMMENSALISM
A symbiotic relationship where one
species benefits, the other is not
affected positively or negatively.
ONE EXAMPLE OF
COMMENSALISM
Birds nesting in a
tree
Certain species of millipede and silverfish inhabit the
nests of army ants and live by scavenging on the refuse
of their hosts, but without affecting the ants.
MUTUALISM
A symbiotic relationship where both
organisms benefit from the relationship.
ONE EXAMPLE OF
MUTUALISM
Bees and flowers
