Which of the following describes the function of agriculture?

The function of agriculture is indeed best described by the systematic growing and harvesting of various organisms. This definition encompasses the diverse range of activities involved in agriculture, which includes the cultivation of crops, the raising of livestock, and the management of resources to produce food, fiber, and other products for human use.

Agriculture is not limited to just a single aspect or type of organism; rather, it represents a broad field that integrates different practices to maximize yield and sustainability. By focusing on systematic techniques, agriculture allows for the efficient use of land and resources, thereby supporting food production on a large scale.

In contrast, other options reflect narrower or unrelated concepts. For example, while conservation of wild species is important and related to environmental efforts, it does not encapsulate the primary function of agriculture, which is a human-driven process focused on cultivation. Additionally, agriculture is not solely centered around fiber production, as it also includes food crops and other plant and animal products. Lastly, while crop rotation is a valuable agricultural practice for maintaining soil health and productivity, it represents just one tactic within the broader framework of agricultural methods rather than a comprehensive description of the field itself.
