Scientists are able to know if the oxygen level in the atmosphere has

changed as a result of plants releasing oxygen during the process of

photosynthesis.

Plants are known as primary producers and they manufacture food through

photosynthesis by utilization of compounds such as Water and Carbon

dioxide to form Glucose and Oxygen which is used by animals.

The oxygen level in the atmosphere is still changing because urbanization

has led to an increase in deforestation all over the world thereby decreasing

the oxygen level. This is why planting of trees have been encouraged to

save the ecosystem.
