The economic sector that includes agriculture is called the primary sector. This sector encompasses industries that extract or harvest natural resources directly from the earth, which includes farming, fishing, and forestry. The primary sector plays a vital role in the economy, providing the foundational resources needed for food production and raw materials for industries. It often serves as the base for secondary (manufacturing) and tertiary (services) sectors. In many developing countries, agriculture remains a significant source of employment and economic activity, while in developed nations, advancements in technology have transformed agricultural practices.
