Agriculture is the science, art, and business of cultivating the soil, producing crops, and raising livestock. It is a fundamental human activity that has been the cornerstone of civilization for thousands of years. The practice of agriculture involves various techniques and technologies aimed at maximizing the yield of crops and animals for human consumption and use. Let's delve deeper into the key aspects of agriculture and its significance.
Types of Agriculture
There are several types of agriculture, including:
Subsistence Agriculture: This type of agriculture is practiced to meet the basic needs of a farmer and their family, with little surplus for sale.
Commercial Agriculture: In this type, crops and livestock are produced primarily for sale, with the goal of generating profit.
Intensive Agriculture: This involves high levels of inputs such as labor, capital, and technology per unit area of land.
Extensive Agriculture: This type of farming requires large areas of land and minimal labor and capital inputs per unit area.

Food Security: Agriculture is essential for ensuring a stable and adequate food supply for the world's population.
Economic Development: It is a major contributor to the economy, providing employment and raw materials for various industries.
The Living Environment: Students understand that cells are the basic unit of life, that all life as we know it has evolved through genetic transfer and natural selection to create a great diversity of organisms, and that these organisms create interdependent webs through which matter and energy flow. Students understand similarities and differences between humans and other organisms and the interconnections of these interdependent webs.
Cells: Students describe how living things are made up of one or more cells and the ways cells help organisms meet their basic needs.
Give examples of organisms that consist of a single cell and organisms that are made of a collection of cells.
