INDIAN GEOGRAPHY

Detailed explanation-1: -Through a process called photosynthesis, leaves pull in carbon dioxide and water and use the energy of the sun to convert this into chemical compounds such as sugars that feed the tree. But as a by-product of that chemical reaction oxygen is produced and released by the tree.

Detailed explanation-2: -Trees give us shade, fruits to eat, wood to make our houses, and leaves to burn on Halloween. They also provide shelter to animals and a home to birds.

Detailed explanation-3: -Explain to students that rainforests are responsible for roughly one-third (28%) of the Earth’s oxygen but a huge amount (from 50% to 85%) of the oxygen in the atmosphere is produced by marine plants. The remaining 2 percent of Earth’s oxygen comes from other sources.

Detailed explanation-4: -While we know trees produce oxygen, there are multiple factors determining how much oxygen each tree type produces. The Leaf Area Index is one way of judging oxygen amounts, according to experts. Bigger trees or those with more leaves tend to produce more oxygen, as do evergreens.

Detailed explanation-5: -The neem tree is the highest oxygen producing tree. It considered a natural pesticide.
