______________________________________________________________________________

Answer 1

Answer:

1. Tropical rainforests are often called the “lungs of the planet” because they generally draw in carbon dioxide and breathe out oxygen. But the amount of carbon dioxide they absorb, or produce, varies hugely with year-to-year variations in the climate.

2. As pants absorb the energy they need through aerobic respiration, which is a chemical reaction that uses the oxygen in the air and glucose within the plant to form carbon dioxide and water. The plant derives the energy it needs to live from the water and carbon dioxide formed by the respiration process, it is necessary for them to respire all the time

Expla

Tropical rainforests are often called the “lungs of the planet” because they generally draw in carbon dioxide and breathe out oxygen. But the amount of carbon dioxide they absorb, or produce, varies hugely with year-to-year vaRespiration in plants happens throughout the day and night thereby carbon dioxide is produced. However, during the daytime, the amount of carbon dioxide released is negligible compared to the amount of oxygen produced as a result of photosynthesis. Hence, one should not sleep under a tree at night.riations in the climate.
