The correct option is (c).
Explanation
Agriculture or farming is viewed as a system consisting of three main components: inputs, processes (operations), and outputs. This systemic approach encompasses not only the cultivation of the soil for growing crops but also the rearing of animals for various products.
Statement-wise Analysis:
- Statement 1 is Incorrect: A farm system is not limited to arable farming (growing crops). It includes pastoral farming and mixed farming. Therefore, crops are not the only output; the system produces a variety of goods depending on the type of farming practiced.
- Statement 2 is Correct: In farm systems that include livestock rearing (animal husbandry), animal by-products are primary outputs. Wool (from sheep) and dairy products (such as milk from cows and buffaloes) are standard outputs of such systems.
- Statement 3 is Correct: Poultry farming is a subset of the agricultural system. Consequently, poultry products, including eggs and meat, are considered valid outputs of a farm system.
Key Takeaway:
The Farm System operates through a cycle of Inputs (seeds, fertilizers, machinery, labour), Processes (ploughing, sowing, spraying), and Outputs (crops, wool, dairy, and poultry products).
