Adaptation of Living Things

Certain animals and plants develop characteristics that help them cope with their environmentbetter than others of their kind. This natural biological process is called adaptation. Among thesuperior characteristics developed through adaptation are those that may help in getting food orshelter, in providing protection, and in producing and protecting the young. That results in the

evolution of more and more organisms（生物体）that are better fitted to their environments.

Each living thing is adapted to its way of life in a general way, but each is adapted especiallyto its own distinct class. A plant, for example, depends upon its roots to fix itself firmly and toabsorb water and inorganic chemicals(无机物). It depends upon its green leaves for using thesun&39;s energy to make food from inorganic chemicals. These are general adaptations, common tomost plants. In addition, there are special adaptations that only certain kinds of plants have.

Many animals have adaptations that help them escape from their enemies. Some are hiddenby their body color or shape, and many look like a leaf or a little branch. The coats of deer arecolored to mix with the surroundings. Many animals have the ability to remain completely stillwhen an enemy is near.

Organisms have a great variety of ways of adapting. They may adapt in their structure, func-tion, and genetics; in their development and production of the young; and in other respects. Anorganism may create its own environment, as do warm-blooded mammals (哺乳动物), whichhave the ability to adjust body heat exactly to maintain their ideal temperature despite changingweather. Usually adaptations are an advantage, but sometimes an organism is so well adapted to a particular environment that if conditions change, it finds it difficult or impossible to readapt to thenew conditions.
