Answer:
Positive feedback system increases temperature of the earth surface which is good in a number of ways.
Explanation: For example, due to increase in the temperature of earth surface, melting of ice occurs in the mountainous area of the world. This stored form of water is changed into liquid form and flows down through streams and used by plants and animals. But more increase in temperature causes rise of sea level which is not good for areas near the sea.

The answer is: B - archaea
Explanation:
The organisms found in the subtropical forests of southern China which were acid tolerant and lacked internal organelles are the Archaea. Archaea refers to the domain of life with organisms living in extreme conditions. Because of this, the Archaea are referred to as the extremophiles.
The cells are very small, prokaryotic and are similar to bacteria in lacking a nucleus and membrane bound organelles. The cell membrane is bounded by a cell wall. They reproduce by binary fission, fragmentation or budding.
They can tolerate high temperatures and survive in hot springs, anaerobic conditions and are acid-tolerant. These acid tolearting Archaea are called the acidophiles surviving in a pH of 2 or less than 2.
They pump out protons out of the intracellular space and thus keep their cytoplasm in a neutral pH or have an acidified cytoplasm. The example are Thiobacillus acidophilus, Crenarchaeota and others.
