\Biological Intercations Biological interactions are the effects organisms in a community have on one another. In the natural world no organism exists in absolute isolation‚ and thus every organism must interact with the environment and other organisms. An organism’s interactions with its environment are fundamental to the survival of that organism and the functioning of the ecosystem as a whole. In ecology‚ biological interactions can involve individuals of the same species (intraspecific interactions)

I was very appalled when I‚ someone who considered himself a totally accepting human being‚ found that I have been living with discrimination lying right under my nose for my whole life. Growing up in a small community in a small country‚ where the majority of the population is white and shares the same typical religion‚ education‚ and social beliefs‚ I had been following the herd instinct. There is a race called Roma in my native town: a slightly dark-skinned people who are considered

is the relationship in which a predator captures and eats its prey. Competition is when more than one organism (or population) tries to use the same limited resource. Symbiosis is a relationship between two species. Mutualism‚ commensalism‚ and parasitism are the three main types of symbiosis. Symbiosis (Mutualism) A boxer crab holds anemone in their claws and uses the stinging tentacles to protect itself from predators. The anemone is benefited in the situation by being able to eat particles of

Symbiosis: The general term used to describe intimate association between pairs of species is symbiosis. Most ecologists further divide the term into three categories‚ i.e. mutualism‚ commensalisms and parasitism. A. Mutualism: Two organisms live together in such a way that both are benefited. This association is usually a permanent one. a. Lichen There are several thousand species of lichen. They are commonly found on exposed rocks and tree trucks. They can even be found on exposed

Impaction Colic is a more serious type. Heavy internal parasitism is one major cause. Along with dehydration‚ excessive ingestion of sand‚ and Enterolith which are stones in
