Prey and Predator

This includes a predator and a prey, herbivore

and parasite-host interactions. The predator eats the prey and the prey gets e

Competition

COMPETITION IS AN INTERACTION BETWEEN ORGANISMS OR SPECIESIN W

THEY WILL COMPETE BETWEEN EACH OTHER FOR LIMITEDSUPPLY OF ATLEAST ONE RESOURCE (SUCH ASFOOD, WATER, AND TERRITORY) USED BY

BOTH CAN BE A FACTOR.

COMPETITION AMONG MEMBERS OF THE SAME SPECIES IS KNOWN AS

INTRASPECIFIC COMPETITION, WHILE COMPETITION BETWEEN INDIVIDUAL

DIFFERENT SPECIES IS KNOWN AS INTERSPECIFIC COMPETITION. COMPET

IS NOT ALWAYS STRAIGHTFORWARD, AND CAN OCCUR IN BOTH A DIRECT

INDIRECT FASHION.

SPECIES LESS SUITED TO COMPETE FOR RESOURCES SHOULD EITHER AD

OR DIE OUT, ALTHOUGH COMPETITIVE EXCLUSION IS RARELY FOUND IN

NATURAL ECOSYSTEMS.

ANIMALS DO COMPETE TO BE THE LEADER OF THEIR TRIBE TOO

Symbiosis

Symbiosisdescribes close interactions between two or more difspecies. It is different from regular interactions between species, symbiotic relationship, the two species in the relationship live togorganisms are involved in symbiotic relationships because this inprovides benefits to both species. However, there are types of sym

are not beneficial and may in fact harm one or both of the species Symbiotic relationships can be obligateor facultative. Obligat

is when two organisms are in a symbiotic relationship because thsurvive without each other. acultative symbiosis is when the spetogether by choice. !here are four main types of symbiotic relatiomutualism, commensalism, parasitism and competition.

Symbiosis-Mutualism

Mutualismoccurs when both species benefit from theinteraction. #ecause mutualism is beneficial for both spinvolved, there are a wide variety of mutualistic interactthese are most common in nature.

or e$ample, there may be a nutritional benefit to be gathe symbiosis, such as with lichen. %ichen is made up oalgae and fungi, and together they provide each other wand structure.

Symbiosis- commensalism

&ommensalism usually occurs between a species that isvulnerable to predation or with an inefficient means oflocomotion, and another species with a relatively effectiof defence. or e$ample certain oby species live amon

spines of to$ic sea(urchins such asAstropyga radiata, sprotection from their host) while a similar relationship o

between a *ellyfish. In both instances the fish benefit, whost is neither advantaged nor disadvantaged by the rel

Symbiosis-parasitism

In a parasitic relationship, the host species is always e$psome degree, although often in such a way that its healthimpaired only slowly. !his allows the parasite to e$ploitover a longer period. Many parasites only spend a portio

lives in the relationship, either to reproduce, or during agrowth stage.

+arasites can be divided into two basic categories,EctopandEndoparasites
