B. Prevention of soil erosion
C. Maintenance of ecological balance
D. All of the above.

Answer 1

An ecosystem is the basic structural and functional unit of nature. In an ecosystem, all living things live in constant interaction with each other and with their environment.

Complete step by step answer:
Ecosystem contains both living and nonliving components. There are several examples of ecosystems around us. Pond, lake, marine ecosystem, desert ecosystem are free examples. This also includes forests. A forest is a large and complex form of an ecosystem in which plants, animals, and other organisms live in constant interaction with each other. There are many species in the forest. Forests all around the globe can be broadly classified into three. They are tropical, temperate, and boreal forests. Among these, tropical forests have the highest species diversity. The forests are of great use to nature as well as for us. Forests contain lots of trees and they release oxygen to the atmosphere. The Amazon rainforests present in the tropical regions are called the lungs of the planet. They reduce pollution and purify the air. They also prevent soil erosion by holding the topsoil by the roots of plants. Forests are home to a large number of animals and birds. It provides food and shelter for them and helps to maintain ecological balance. It also affects the climate and maintains biodiversity.
Hence the correct option is D.

Note: Even though forests are so important for us, an alarming level of deforestation happens today. In order to prevent this, there are several organizations that work to protect forests and other ecosystems. One such program is the Man And Biosphere Programme (MAB) by UNESCO.
