Make a summary (precis) of the following passage in not more than 70 words, Abstract the main idea of the passage and give it an appropriate title.

All ants have a very varied diet. This is a strong point in the struggle for a livelihood, as it enables them to use whatever food is, for the time abundant and easy to find and colledt. In this way a varied diet cushions them against unpredictable changes in food supply. All our species eat some sort of prey, but they will also pick up crumbs of cake, cheese, bread or fruit that they find lying about near picinc sites or in parks or gardens.

Ants eat worms, centipedes and spiders; they also eat insect larvae, and insect adults such as flies, moths & spring-tails. Such small animals do not all make easy game for ants; they are usually much quicker than the ant itself and they have an extraordinary number of ways of escaping. Some flick their bodies violently; and some give out a pungent repellent substance.

If ants, or indeed any hunting animal were too clever at catching their prey they would eventually destroy the species completely and suffer themselves in turn. That is one reason why in nature, it is usually the weak and disabled that are caught and eaten. The well-formed, alert, vigorous ones can escape and survive to keep the species going. The prey avoids destruction in this way, and maintain a good breeding stock which provides a regular food supply for its predators. The predators can even be thought of as beneficial agent that prevents over crowding of the prey by clearing up all the superfluous individuals.

Title : Struggle for Livelihood

Summary : Food habit of different species is so that they can survive and let other species survive too. For example ant is habituated to whatever is available and survive during adversities. A species, which is the prey of another species, adopts different methods for survival. It is usually the weak and disabled that are caught and eaten. The fittest could escape and survive. In this way the prey avoids destruction. If the prey animals are totally destroyed, then it would be impossible for the animals which live on them to survive. Therefore, a balance is struck so that different species could avoid extinction.
