Everyone needs a home, people and other animals share some basic needs. All animals need a place in which to live, and the environment in which an animal lives is called a habitat. In an animals habitat is food, water, shelter, adequate space in an arrangement appropriate to the animals needs. If these components are altered or no longer suitable it can cause an impact. Some of the limiting factors that may cause an impact are disease, predation, pollution, accidents, and climactic conditions.
The interrelationship comes about due to the interdependencies between plants and plants, plant and animals, as well as animals and animals. The interrelationships and relationship between the two variables is very important.
When we think of interdependency the term symbiotic comes to mind. A symbiotic relationship occurs when two species of organisms live in close physical contact with each other. There major types of symbiosis are commensalism, mutualism and, and parasitism .
In a commensalism relationship one species obtains food or shelter from another species without seriously harming that organism or providing any benefits in return.
A mutualistic relationship in which two different species live in a symbiotic way where both species benefit in a symbiotic way where both species benefit and are dependent upon the relationship.
Parasitism relationship is a relationship between two species in which the parasite species is nourished at the expense of the host species.
Habitat provides shelter and a place to reproduce. A habitat can be small or very large. The entire ocean is the habitat of the whale. In the habitat of animals they have a role to perform in that community. The job or role is called the organism’s niche. Even though organisms may share the same habitat, their niches may and does differ.
Succession describes the ever changing environment and the gradual process by which one habitat replaces another. Changes in an environment trigger changes in plant and animal population. A pond may be transformed into a marsh, then a forest over a thousand years. Environments are not static but ever changing.
Extinction is a natural process. Excessive and intensive human activity can cause an acceleration in an environment extension of various forms of life.
