Without oxygen, life cannot be sustained as it is an essential reactant in the respiration process. So the evolution of photosynthesizing bacteria increased the amount of oxygen in the atmosphere through converting water and carbon dioxide into oxygen with the help of sunlight. This provides a suitable environment for plants and vegetation to grow; plants also photosynthesise so they encouraged the increase of oxygen in the atmosphere even further, sustaining a suitable environment for the Animalia kingdom to evolve. Thanks to this, we now have a huge range of different modern species of animals and plants.

Answer:
Energy flow in an ecosystem is unidirectional. It means that energy which is absorbed by the producers from sun and is converted into chemical energy, always flow from a lower trophic level to a higher trophic level as in a food chain when herbivore consumes producers the energy is transferred from producers to consumers and so on. Some of this energy is assimilated some is used by the organism and some is dessipated in the environment but the flow of energy is never reverted, that is obviously a producer can not consume a consumer.
