Herbivores are animals that feed exclusively on plant matter.

Consumers that feed on tertiary consumers are at the fourth trophic level. These are defined as quaternary consumers.

Herbivores are the kind of animals whose diet comprises of solely plants. There are different types of herbivores. They further divide into the category of insect herbivores and mammalian herbivores.

Cats are carnivores, meaning they require meat in their diet and need little carbohydrates. In the wild, cats usually prey on small animals, such as mice and birds. 

Humans consume both plant-based and animal-based foods. This dietary habit classifies them as omnivores.

Humans are biologically classified as omnivores because they possess the physiological capacity to derive nutrients from both plant and animal sources.

Animals that feed on herbivores are primary carnivores, which occupy the secondary consumer trophic level.

Herbivores are animals that feed exclusively on plant materials.

Ruminants are exclusively herbivores.

Rice and other foodgrains are agricultural products derived from crops, which are plants. They are primary producers in the food chain.

Inorder to feed a largely populated country like China, the food resources should be easily cultivated and nutritionally rich. 

 Breeds which have the higher capacity for milk production are called milch breeds. The milk producing female livestock animals are called as dairy animals or milch animals e.g., cows, buffaloes, goat and sheep. Thus, the correct answer is option D.

Oil/ ghee can be extracted from both animal products and plant products. Ghee is prepared from boiling and clarifying the milk fat. Hence, it is extracted from an animal source.
