Crop which are primarily grown to provide food for farm animals are

This question is asking about crops that are primarily grown to provide food for farm animals. The options are Legumes, Weeds, Forages, and Grasses.

Legumes are a group of plants that have the ability to capture nitrogen from the air and convert it into a form that can be used by plants. They are often used as a source of protein in animal feed, so they can be grown to provide food for farm animals.

Weeds, on the other hand, are unwanted plants that grow in fields and compete with crops for nutrients, water, and sunlight. They are not intentionally grown to provide food for farm animals.

Forages, which is the correct answer, are crops that are specifically grown to provide food for livestock, such as cattle, sheep, and goats. They are usually high in fiber and are often grazed or harvested as hay or silage for animal feed. Forages can include grasses, legumes, and other plants that are suitable for animal consumption.

Grasses, the last option, are a type of plant that is commonly used as forage for livestock. They are often grazed by animals or cut and dried as hay. However, not all grasses are grown primarily for animal feed, so this option is not the best answer.

Therefore, the correct answer to this question is C: Forages, as they are crops that are primarily grown to provide food for farm animals.
