Classification of animals on the basis of food - class-VII

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.

Hawks, lizards, owls, and cats are carnivores that feed on primary consumers (herbivores). Therefore, they are classified as secondary 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. Mammalian herbivores are found in abundance. They include cows, deer, horses, sheep and more. Hence, correct option is B.

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.

Omnivores have a more diverse diet than herbivores or carnivores, requiring a wider array of enzymes to digest various substrates like cellulose, starch, and proteins. This leads to a higher diversity and number of metabolic enzymes.

Organisms that feed on dead organic matter are known as scavengers or detritivores. Scavengers specifically feed on the remains of dead animals.

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

Detritivores are organisms that feed on detritus, which includes organic material from various sources including plants and animals. Omnivores are often included in broader ecological classifications of feeding habits.

Macro consumers are heterotrophic organisms that ingest other organisms or organic matter, which includes herbivores, carnivores, and omnivores.

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

Man is an example of omnivorous animal because Omni means all and vore means eater. An organism which can feed on the plant, as well as the meat of the animal, are called omnivorous.

Humans consume both plant and animal matter, which classifies them as omnivores.

Omnivorous is an animal or person that eats a variety of food both plant and animal origin.

The first torphic level contains the producers which are plants.

Herbivores depend on plants for their nutrition and are hence known as primary consumers and they cannot synthesize their own food.

Herbivores are animals that feed exclusively on plant materials.

Ruminants are exclusively herbivores.
