The correct answer is: d) All of the above.
Many tribal communities in Tamil Nadu traditionally depend on shifting cultivation, collection of forest produce, and hunting and gathering.
Shifting cultivation is a type of agriculture in which land is cleared and used for a short period of time, then abandoned and allowed to regenerate. This type of agriculture is often used by tribal communities in tropical forests.
Collection of forest produce includes activities such as gathering fruits, vegetables, nuts, and honey from the forest. It also includes collecting non-timber forest products such as bamboo, rattan, and medicinal plants.
Hunting and gathering is the practice of hunting animals and gathering wild plants for food. This type of subsistence is often practiced by tribal communities in remote areas.
All of these activities are important for the survival of tribal communities in Tamil Nadu. They provide food, shelter, and medicine. They also help to maintain the balance of the ecosystem.
However, these activities are also under threat from deforestation, development, and other human activities. It is important to protect the rights of tribal communities and to ensure that they have access to the resources they need to survive.
