The fossil history of animals goes back about 600 million a long time to your Ediacaran period, or relatively previously.

Hydrothermal vent mussels and shrimps Most animals count on biomass and bioenergy produced by crops and phytoplanktons (collectively named producers) by means of photosynthesis. Herbivores, as Main individuals, try to eat the plant content directly to digest and take up the nutrients, even though carnivores along with other animals on higher trophic degrees indirectly get the nutrients by consuming the herbivores or other animals which have eaten the herbivores.
