Answer
All the plants and animals in an area are inter-dependent and interrelated to each other in their physical environment, thus, forming an ecosystem. Ecosystem is a system of inter-dependence comprising the physical environment and the organisms living within.
Plants, animals, human beings and the environment are the components of ecosystem. Plants are the main natural component on the earth which can use the sun's energy to prepare food. Plants are the backbone of the natural resources of the country.
The nature of plants in an area, to a large extent, determines the animal life of that area. When the vegetation is altered, the animal life also changes.
Human beings are also an integral part of the ecosystem. They utilise the vegetation and wildlife. All the living beings on the earth are dependent on plants directly or indirectly.
