The y have to have carbon dioxide to make oxygen
The animals die and the chemical goes into the soil for the plants and when the animals eat the plants the chemicals are passed back to the plants.
oxygen is required by our body. Plants breathe out Oxygen.
we will die because there is no oxygen to breathe in
The amount of Oxygen started to increase as more plants and animals appeared. The plants took in Carbon dioxide and gave out Oxygen. So, overtime the amount of Carbon dioxode (which was high) decreased, and oxygen increased.
Plants release oxygen .
Carbon Dioxede is the air that we breathe out.After that,the plants will breath in and gave us oxygen.Anyway,oxygen is the air that we breathe in.
Yes, photosynthesis in plants releases Oxygen.
yes plants can be manufactured for oxygen
It can kill plants if the plants just get oxygen. This can lead to the killing of human sf all plants were exposed to was oxygen.
Oxygen
