Trees, The Best, or Worst Oxygen Producer

          Trees are the best plants produced by mother nature. They grew from seeds, then they suck up carbon dioxide for photosynthesis then as a byproduct they let out oxygen. Trees also produce flowers, leaves, wood and fruits, that are also beneficial to humans, animals, and insects alike. Animals eat the fruits or leaves, humans eat the fruits and use the wood for construction, insects eat the flowers nectar to pollinate and/or make honey.
