Ms. greene's ecology class compared landsat images of arkansas' loblolly-shortleaf pine forests dated 1985 through 2005. there was an obvious decrease in the square miles of pine forests. all but one reason below would explain this decrease. that is a) fires. b) logging. c) urban sprawl. d) habitat destruction.

Correct A). Fire  

The forest fire is an uncontrolled fire that occurs in nature. Sometimes it is so strong that it takes a lot of time for the firefighter to have control. It results in the huge destruction of vegetation. It is caused by two ways mainly by the lightning or by the human cause. The natural cause of forest fire is sawdust and leaves that are caused by lightning and spontaneous combustion of dry fuel.

Hence, the correct answer would be option A.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
