Through cellular respiration humans release carbon dioxide (CO2) into the atmosphere. This CO2 is used by plants during photosynthesis. During photosynthesis plants release oxygen (O2) into the atmosphere. The oxygen is used by animals in order to carry out cellular respiration.

the level of oxygen is maintained in air by respiration in plants and animals and by photosynthesis in plants. It is maintained by the air cycle which is very similar to the water cycle. We inhale that oxygen and release carbon dioxide which plants take during this process.

Plants maintain the atmosphere. They produce oxygen and absorb carbon dioxide during photosynthesis. Oxygen is essential for cellular respiration for all aerobic organisms. For example, through transpiration, plants move enormous amounts of water from the soil to the atmosphere.

Plants make their food in a process called photosynthesis. Once they have water and carbon dioxide, they can use energy from sunlight to make their food. The leftovers from making the plant food is another gas called oxygen. This oxygen is released from the leaves into the air.

We need plants for basic human purposes. We eat them in many forms; we make medicines, soaps, furniture, textiles, tyres and much more from them. Plants play a very important role in our lives. Although we now live in a highly industrialised society, we have not lost this dependence on plants.

They give us clean water to drink, air to breathe, shade and food to humans, animals and plants. They provide habitats for numerous species of fauna and flora, firewood for cooking and heat, materials for buildings and places of spiritual, cultural and recreational importance.

Importance of Trees They are important because they give us fresh air to breathe, food to eat and shelter/shade from sunlight and rainfall. Besides this, there are many medicines in the market that are made up of trees extracts. Apart from this, there are plants and trees that have medicinal value.

What’s the Solution? We Need Animals! When humans destroy animal habitats, most do not realize the long-term impact their actions have on the environment! Often, animals play a crucial role in keeping insect populations in check, protecting humans from floods, and maintaining the health of their ecosystems!

Without trees, formerly forested areas would become drier and more prone to extreme droughts. When rain did come, flooding would be disastrous. Massive erosion would impact oceans, smothering coral reefs and other marine habitats.
