There are five major components of food namely vitamins, minerals, proteins, carbohydrates and fats. While the diet of carnivores is rich in fats and proteins, there are some necessary vitamins and minerals in plant-based foods that their diet lacks. Similarly, an all plant-based diet lacks in a good amount of protein and certain minerals.
It is important to know that there is difference between vegetarians and herbivores. While vegetarians make a conscious decision to not eat meat, herbivores on the other hand are incapable of eating meat and dairy products. Similarly, carnivores lack the necessary enzymes in their stomachs to digest cellulose which is a major component of green food like grass.
Nectar: The juicy sweet liquid secreted by within flowers which is sucked by bees and is made into honey by them
Sprouting: The process by which seeds shoot out small white structures as way of growth is called Sprouting.
