Bees visit flowers to collect nectar and pollen which they use to make honey as a food. As bees fly around from plant to plant they pick up and drop off pollen between the flowers. This is a really important job in nature because moving pollen between flowers helps plants to reproduce (make new plants) through a process called pollination. If bees didn’t do this, then certain types of plants wouldn’t be able to make seeds.

All living things need oxygen in order to stay alive but plants, algae and a group of bacteria called cyanobacteria, can also make oxygen. These plants, algae and cyanobacteria make more oxygen than they use and the extra oxygen goes back into the air. So, the oxygen is sort-of recycled, rather than used up.

Plants like trees use their leaves to make oxygen. But what if there were no trees left on Earth – would there still be enough oxygen in the air for us to breathe?
