Science Tip of the Week -- Symbiosis of Plants and Animals


Plants and animals have a symbiotic relationship. This means that they are different from each other, but they each have something the other needs to survive.


Animals and people breathe oxygen and release carbon dioxide. Plants take in carbon dioxide and release oxygen.


Plants also provide food for animals, and animals fertilize the plants in return.


Animals - even carnivores (meat eaters) - would not be able to survive without plants, and plants would not be able to survive without animals.
