An omnivore is an organism that regularly consumes a variety of material, including plants, animals, algae, and fungi. They range in size from tiny insects like ants to large creatures—like people. Human beings are omnivores. People eat plants, such as vegetables and fruits.

Herbivores Characteristics

• They feed specifically on plants.
• They require sufficient energy to survive.
• Herbivorous animals start digesting the food as soon as it enters the mouth due to the acidic saliva.
• Few herbivores have a pair of sharp-edged, broad front teeth which helps in gnawing food products.

Herbivores are animals whose primary food source is plant-based. These animals have evolved digestive systems capable of handling large amounts of plant material. Herbivores can be further classified into frugivores (fruit-eaters), granivores (seed eaters), nectivores (nectar feeders), and folivores (leaf eaters).

Examples of large herbivores include cows, elk, and buffalo. These animals eat grass, tree bark, aquatic vegetation, and shrubby growth. Herbivores can also be medium-sized animals such as sheep and goats, which eat shrubby vegetation and grasses. Small herbivores include rabbits, chipmunks, squirrels, and mice.

List of carnivores

• Felines, ranging from domestic cats to lions, tigers, and other large predators.
• Some canines, such the Gray Wolf but not the Red Wolf or coyote.
• Hyenas.
• Some mustelids, including ferrets.
• Polar Bears.
• Pinnipeds ( seals, sea lions, walruses, etc.)
• Birds of prey, including hawks, eagles, falcons and owls.

The cat family, including lions, tigers and small cats, for example, are obligate carnivores, as are snakes, lizards and most amphibians. Many hypercarnivores, including some members of the Carnivora order, have heavy skulls with strong facial musculature to aid in holding prey, cutting flesh or grinding bones.

The most common acute toxins that kill horses in a few hours to 36 hours include:

• Botulism – often associated with haylage feeding.
• Ionophore toxicity – associated with feed contamination.
• Yew toxicity – associated with horses consuming clippings from this common ornamental shrub.
• Poison-hemlock – found in swampy areas.

It is a fact-filled analysis which reveals how humanity has known about meat-eating horses for at least four thousand years, during which time horses have consumed nearly two dozen different types of protein, including human flesh, and that these episodes have occurred on every continent, including Antarctica.
