Animals are basically divided in three categories on the basis of food they eat. These categories are as:-
•Herbivores
•carnivores
•omnivores
Let we discuss each of them in details:-
1. Herbivores:- Animal that feed of plant and plant products only. These animals only eat plants and their products. Plant product include( fruits , Vegetables etc)
These animals rank at first level of food chain . You can also called them as "vegetarian". These animals basically eat healthy food and thus have low toxicity in their body .
They basically eat grasses , leaves of trees , branches etc.
Examples of herbivores :- Deer , cow , buffalo , goat , Giraffe etc.
2. Carnivorous :- Totally opposite to harbivores animals . They eat flesh of other animals only . They rank at second number of food chain. For example :- grass ------deer-----lion and lion is a example of carnivorous animals.
They totally depends on animal and their products . You can also called them as NOn - vegetarians.
Examples of carnivorous :- lion, tiger, dogs , jackals etc.
The third category as according to the question is of omnivorous . Omni means "both". So as per name they eat both plants , plants products and animals too.
They eat according to their circumstances . They can be dependent on both to fulfill their requirements.
For example :- bear eat plants leaves and fish both.
We humans are also omnivorous. We loves to eat both plants products and animal products too.
So , this is basically the third category @omnivores animals. Hope you will be satisfied with my answer.
