Answers
Answer:
Living things need oxygen to survive because we can't survive without oxygen. It is vital that living things respire to get the oxygen for living cells to function. Without air, there is no life. Plants use Carbon Dioxide (together with sunlight and water) to produce energy and give out Oxygen as a by-product.
Since air is invisible we easily forget that it is all around us. When we blow air in a balloon, we can feel the air pushing on the balloon. It's the same with a tire or basketball. When we sit in front of a fan, we can actually feel the air molecules moving in the same direction.
Animals need oxygen from air to carry out the reactions that release and transform energy from food. Carbon dioxide is released as a waste product during these processes. ... Fish and many other aquatic animals use gills to absorb oxygen from water.
