Basic Of Environment

We have heard the word ‘environment’ often being used on the television, in newspapers, and by people around us. Our elders tell us that the ‘environment’ is not what it used to be earlier; others say that we should work in a healthy ‘environment’, and global summits involving the developed and developing countries are regularly held to discuss ‘environmental’ issues.

In this chapter, we shall be studying how various components in the environment interact with each other and how we impact the environment.

Eco-Sytem What Are Its Components?

All organisms such as plants, animals, microorganisms, and human beings as well as the physical surroundings interact with each other and maintain a balance in nature.

All the interacting organisms in an area together with the non-living constituents of the environment form an ecosystem. Thus, an ecosystem consists of biotic components comprising living organisms and abiotic components comprising physical factors like temperature, rainfall, wind, soil, and minerals.

For example, if you visit a garden you will find different plants, such as grasses, trees; flower-bearing plants like rose, jasmine, sunflower; and animals like frogs, insects, and birds.

All these living organisms interact with each other and their growth, reproduction, and other activities are affected by the abiotic components of the ecosystem.

So a garden is an ecosystem. Other types of ecosystems are forests, ponds, and lakes. These are natural ecosystems while gardens and crop fields are human-made (artificial) ecosystems.
