Question

Environment introduction

Answer 1

Environment is defined as the surroundings in which the organism lives. The environment may be the physical environment, the chemical environment or the biological environment. Thus, the environment has two components - abiotic and biotic.

The abiotic environment includes the air (atmosphere), water (hydrosphere) and land (lithosphere). The biotic environment includes the plants, animals and the microbes.

Organisms are dependent on the environment to fulfil their needs; man is also constantly interacting with the environment in order to fulfil his needs. These needs include the basic needs of oxygen, food and shelter in addition to the social needs like entertainment, medicines, etc. The things that man requires for his survival and comfort are called the resources. The environment is a reservoir of resources. Maintaining the natural resources of the environment and their careful use is called conservation. The conservation of environment involves the conservation of the natural resources.

A healthy environment is an absolute necessity for the well-being of all organisms, including man. All our needs, big and small are being met by the environment. However, man having reached the pinnacle of evolution is trying to bring about changes in the environment to suit his convenience. Unfortunately, this convenience is temporary. In the long run, man is losing out on a healthy environmen

Answer 2

Environment is what is around something. It can be living or non-living things. It includes physical, chemical and other natural forces. Living things live in their environment. They constantly interact with it and change in response to conditions in their environment. In the environment there are interactions between animals, plants, soil, water, and other living and non-living things.
Things in the natural environment that we value are called natural resources. For example; fish, sunlight, and forests. These are renewable resources because they come back naturally when we use them. Non-renewable resources are important things in the environment that are limited for example, ores and fossil fuels. Some things in the natural environment can kill people, such as lightning.

Everything is surrounded by other things, so everything is the environment of something. This includes the biotic and abiotic factors that influence each other. Living elements: animals, plants, etc. are biotic elements, abiotic elements include air, water, sunlight etc. Studying the environment means studying the relationships among these various things.

Ecological units which are natural systems without much human interference. These include all vegetation, microorganisms, soil, rocks, atmosphere, and natural events.
Universal natural resources and physical phenomena which lack clear-cut boundaries. These include climate, air, water, energy, radiation, electric charge, and magnetism.
