The condition that is not necessary for germination is "zero temperature." All seeds require an optimum temperature range for successful germination, which varies among different plant species. While some seeds may require a specific temperature, such as stratification or scarification to overcome dormancy, no seeds can germinate at zero temperature. Therefore, the correct statement is: The following conditions are necessary for germination except zero temperature: - adequate moisture - viable seed - optimum temperature

The nutrient class that is used only for energy production in farm animals is Carbohydrates. While all nutrient classes can be sources of energy for animals, carbohydrates are particularly important for providing energy quickly and efficiently. Proteins and minerals are primarily used for building and repairing tissues and structures in the body, while fat and oil serve a variety of functions including energy storage, insulation, and as building blocks for certain hormones.

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 vertical section of the soil showing a series of horizontal layers of different types of soil is called a "Soil profile".

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.

The correct answer is: Weeding. "Weeding" refers to the process of removing unwanted plants from a farm or garden to help the desired plants grow better. "Thinning" usually refers to the removal of excess plants to allow the remaining plants to grow stronger and healthier. "Mulching" refers to the practice of covering the soil with a layer of material (such as leaves, straw, or bark) to retain moisture, suppress weed growth, and improve soil quality. "Supplying" does not relate to the removal of unwanted plants on a farm. It could refer to the act of providing necessary resources, such as water or nutrients, to the desired plants.

Malnutrition is said to occur when a ration does not provide all the food nutrients in adequate quantities needed by an animal.

The process that is not used in rice processing is fermentation. Threshing is the process of separating the grain from the straw, while winnowing is the process of separating the chaff from the grain. Perboiling involves partially boiling the rice in the husk, which results in increased nutritional value and easier removal of the husk. Fermentation is a process used in the production of certain types of alcoholic beverages and some food products, but it is not a typical step in rice processing.

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.

The quantity of ration that can supply the required nutrients above the maintenance to enable the animal to produce the form of animal product for which the livestock is kept is known as a "production ration."

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.
