How do animals contribute to maintain the ecological balance

Answer 1

bacteria like rhizobium provide nitrogen to plants, other type of microbes help in decomosition, humans and animals eat plants some other carnivores animals depend on herbivores/omnivores animals for food. if there were only herbivores animals the plant cover would be less if only carnivores animals were there they would not have any food to eat and if there were no microbes the decomposition of some things was not possible and the provision of nitrogen wouldn't have been there.
