The gradual abundance of oxygen (by product of photosynthesis) made it possible for aerobic organisms to grow more and evolve.
Hope that helps!
It is very interesting how photosynthesis and cellular respiration<span> help each other. During photosynthesis, the </span>plant<span> needs carbon dioxide and water-- both of which are released into the air during </span>respiration<span>. And during </span>respiration<span>, the </span>plant<span> needs oxygen and glucose, which are both produced through photosynthesis!
