Plants absorb the carbon dioxide, that humans and animals breathe out, through tiny pores in their leaves and stems, and draw up water from the soil. Using the light energy from the sun, the plants transform this carbon dioxide and water into food and oxygen. The oxygen is released through the tiny pores. Plants are very important as they transform the carbon dioxide we breathe out into oxygen we need to breathe in. So when a tree is cut down it reduces the number of plants producing oxygen.

This enormous animal might look dangerous, but is in fact a harmless animal which filters a swimming pool of water every hour.
