Question

What's supports life and is thus called the living world?​

Answer 1

Answer:

Explanation:

This chapter discusses the living world including plants and animals. Living things show movement, responsiveness to the surroundings, assimilation, growth with development, and reproduction. A mammal has a complicated body, which is maintained at one temperature, whatever the surrounding temperature might be. Man is a mammal. The simplest forms of life consist of one cell. All other living things are composed of a number of tiny living cells, grouped in definite patterns to form whole bodies. A unicellular organism consists of only one tiny cell, in which all living processes take place. A multicellular organism consists of many cells, grouped into tissues and organs and coordinated to act as a single living thing. All living cells— plant and animal—have several main parts. The cytoplasm and the nucleus together are known as the protoplasm, the living matter of the cell. Living things are confined to a narrow region near the surface of the earth. It is because the activities of cells can occur only where there is abundance of sunlight, carbon dioxide, water, oxygen, certain salts and a temperature range between 0° C and 90° C.
