The type of ration that supplies the animal with just the quantity of nutrients that are enough to enable the animal to carry on with vital body activities without losing or gaining another substance is called the "maintenance ration." A production ration is designed to provide nutrients for specific animal production goals, such as milk production or weight gain. A balanced ration is formulated to provide all the necessary nutrients in appropriate amounts to meet the animal's needs. A measured ration is a ration in which feed ingredients are weighed or measured out in specific amounts to meet the animal's nutrient requirements.

Seeds are raised in the nursery for several reasons, including: - To protect them from harsh environmental conditions, such as extreme temperatures or heavy rain, which could damage or kill the seeds. - To provide them with a controlled environment with optimal growing conditions, such as the right amount of water, nutrients, and light. - To monitor and manage pests and diseases that could harm the seeds. - To allow for easier transplanting and handling of the seedlings once they are ready to be moved to their final growing location.

Stumping operation involves the use of farm tools like the cutlass, spade, mattock, ax, bull-dozer, etc, to manually or mechanically remove or uproot the base of trees and shrubs. This is done to compose cultivation easier and free from obstruction.

Poisoning is not a commonly used fishing method and is generally considered unethical and harmful to the environment. The other three techniques, netting, trapping, and hooks and lines, are commonly used methods in fishing.

The problem that is usually not associated with subsistence agriculture is "it requires a large area of land." Subsistence agriculture is typically practiced on small plots of land and involves growing crops and raising livestock for the sole purpose of feeding one's family, without generating any surplus for sale. The other three problems mentioned (unreliable family labour supply, use of simple tools, and lack of surplus for sale) are all commonly associated with subsistence agriculture.

Planting weed is not a basic consideration in planting operations. The other options listed are all important factors to consider when planting, as they can affect the growth and development of the plants. Planting space determines how far apart to plant the seeds or seedlings, which affects how much space the plants will have to grow and how much light, water, and nutrients they will receive. Planting time is important because different plants have different requirements for temperature and moisture, and planting at the wrong time can result in poor growth or even the death of the plants. Planting depth is important because different seeds require different depths to germinate properly, and planting too shallow or too deep can affect the germination rate and the growth of the plants.

The pig has a digestive system which is classified as monogastric, or nonruminant. Humans also have this type of digestive system. They have one stomach (mono = one, gastric = stomach). The monogastric differs from that of a polygastric, or ruminant, digestive system found in cattle and sheep.

The main function of an Agricultural Extension Officer is to pass information or new innovation from the research institute to the farmers, not just pass information but sometimes also demonstrate how to use these information. They are like and intermediary between the researchers and the farmers.

The climatic factors which affect organisms include air, sunlight, and rain. Rocks are not a climatic factor, although they can indirectly affect organisms through their impact on soil composition and drainage patterns.
