The world is composed of different species with varying level of abilities and power. While others are inferior, to be gorged and destroyed is their fate, some are superior, and they gorge and destroy. This is the law of nature. The strongest dominates and the weakest is trampled.

A relationship in which one organism feeds on the tissues or body fluids of another organism is parasitism. In parasitic relationship one member benefits and other is harmed. The member that benefits in a parasitic relationship is the parasite, and the member that is harmed is the host.

If your dog or cat has had fleas or worms, you have had experience with parasitism. Usually a dog or cat is only need uncomfortable with flees, which live outside the host. But other parasite, such as tapeworms in an animals and mistletoe in plants, can weaken or kill the host. And increase in a parasite population can cause a decrease in a host population. However as the availability of host’s decreases, the parasite population is also controlled.

But, parasite can spread easily in a crowded host population. Termites are parasite that live in trees and eat the cellulose present in trees. Parasite are the detrimental to their host’s health, sometimes causing its death. Example of parasites include leeches, lice and flees.

The struggle for the survival is a natural phenomenon of the earth. Each species’ aims of existence are to perpetuate his own kind. Thus, creatures have to breed or they will perish. Once the young were laid, they will search for a green pastures were they can abundantly feed themselves and their new –born. Once found, the hunt is on.

Hence, a cheetah chases a gazelle. An orb-web spider bundles of a grasshopper that has blundered into its web. Pangolin it’s as many as 200,000 ants in one night. A gray seal pursues a fish through the water. A tiger catches and kill a spotted deer. A red-backed shrike caught a lizard and impales it on its thorn ‘larder’.

All these things took place because they have to. Unless you have flunked and consume a lower form of species, your existence may be threatened. Nevertheless, in the stringent world of predation, predators may also miss a kill. In this case, the hunted has its way out.

Anything you want you can have if then behaviour is right. The fight for the survival is continual battle of wit between the hunter and the hunted. Proper conduction of things along side with proper behavioural bearing is requirements if a predator would want to secure a successful hunt. On the other hand, the timely use of senses and vital strategy should be posses by the prey to avoid being eaten. A gazelle might have strong legs for escaping but if it would not run for its life, it surely would be caught and killed.
