Food Production and Management

Plants are autotrophic, meaning they can produce their own food using sunlight, water, and carbon dioxide through the process of photosynthesis.

Cotton is a fibrous crop because it is harvested for its fibers, which are used to manufacture textiles. The other options are food or sugar crops.

Ploughing (or tilling) is the process of loosening and turning the soil, which is the first step in preparing a field for cultivation to allow roots to penetrate deeper.

Levelling is the process of making the soil surface even. This is crucial for uniform sowing of seeds and efficient distribution of water during irrigation.

Weedicides are specific chemicals used to kill or inhibit the growth of unwanted plants (weeds) in a field without harming the main crop.

Pesticides are chemical substances used to control, repel, or kill pests, including insects that damage crops.

Photosynthesis is the biological process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water.

Agriculture is the science, art, and practice of cultivating plants and livestock for food, fiber, and other products used to sustain human life.

Kharif crops are monsoon crops that are sown at the beginning of the rainy season (June) and harvested at the end of the monsoon season (October).

Dairying is a branch of agriculture that involves the management and rearing of milk-yielding animals like cows, buffaloes, and goats.

Threshing is the process of separating grain from the harvested crop stalks. Option B correctly identifies this process, though it contains a typo. The other options describe different agricultural operations like spraying pesticides or adding manure to fields.

Poultry farming is the practice of raising domesticated birds such as chickens, ducks, turkeys, and geese for the purpose of farming meat or eggs for food.

Fish liver oils, such as those from sharks and cod, are well-known natural sources of vitamins A and D.

Apiculture, or beekeeping, is the maintenance of honey bee colonies, commonly in hives, by humans for the production of honey and other products.

Draught animals are animals that are kept and trained to perform work, such as pulling carts, ploughing fields, or carrying heavy loads.

A combine harvester (or simply a combine) is a machine that performs the three main harvesting operations: reaping, threshing, and winnowing, in a single process.

Harvesting is the agricultural process of gathering mature crops from the fields. Tilling involves preparing the soil, while irrigation refers to the artificial application of water to land.

Honey is primarily composed of simple sugars, specifically glucose (also known as dextrose) and fructose. Dextrose is the common name for the D-isomer of glucose.
