CO2 is an important trace gas in Earth's atmosphere. It is an integral part of the carbon cycle, a biogeochemical cycle in which carbon is exchanged between the Earth's oceans, soil, rocks and the biosphere. Plants and other photoautotrophs use solar energy to produce carbohydrate from atmospheric carbon dioxide and water by photosynthesis. Almost all other organisms depend on carbohydrate derived from photosynthesis as their primary source of energy and carbon compounds.
In this question, there are no options provided. I would try and answer this question from my knowledge and hope it helps you. High erosion rates in Madagascar are caused primarily by slash and burn treatment of forests. This leads to the upper soil becoming very loose and they get eroded very easily. This leads to unfavorable condition for farming.
A. Used fire to do controlled burns
The result of controlled burns were highly beneficial to both the Aborigines and the environment. The burnt remains of the burns were very fertile and encouraged the growth of new vegetation that would not have been able to flourish if the older growth had not been removed. The removal of old vegetation also resulted in a low chance of wild fires. Further more new vegetation was able to attract wildlife to graze, making hunting easier.
The concept of controlled burns is still used today and was/is also practiced by First Nations in North America.
A fact is a statement that is true and can be verified objectively, or proven. In other words, a fact is true and correct, no matter what. An opinion, however, is a statement that holds an element of belief; it tells how someone feels. An opinion is not always true and cannot be proven.
