What Symbiotic Relationships Are
Symbiotic relationships are a special type of interaction between species.
Sometimes beneficial, sometimes harmful, these relationships are essential to
many organisms and ecosystems, and they provide a balance that can only be
achieved by working together.
Symbiosis
Def: the relationship between two different kinds of living
things that live together and depend on each other to
survive. I.E, a plover bird has a symbiotic relationship with
a crocodile because the plover bird eats the tiny bits of
food stuck in the crocodile’s mouth, which completes it’s
diet. Also, it leaves the crocodile infection free.
Mutualism
Mutualism, association between
organisms of two different species in
which each benefits. Mutualistic
arrangements are most likely to develop
between organisms with widely different
living requirements
The plant benefits from the ants because their pollen spreads
more of it just by transportation
Commensalism
Commensalism is a form of interaction/survival in between to
organisms without harming one another. The smaller species
may obtain shelter, locomotive, food, and support.
EX. Remoras benefit from the shark because they provide
remoras with food, protection and transportation.
Parasitism
Def. A relationship between two species of plants or animals
in which one benefits at the expense of the other.
Ectoparasites- Ticks, fleas, leeches, lice, etc. They
commonly cause disease because they live on the outside of
the host, but not within the body.
Endoparasites- Bacteria/Viruses. They rely on a third
organism, known as a vector to transmit the virus to the
host.
The tongue-eating louse benefits because it eats the fish’s
tongue , then continues to eat the food the fish tries too
eat. Costing the fish a meal, and causing it to starve.
