Answer:
frequency of allele “A” is .39
frequency of allele “a” is .77
Explanation:
hardy weinberg equation
p^2 + 2pq + q^2 = 1 or (A+a)^2
p^2	=  (AA)
2pq	=  (Aa)
q^2	=	(aa)
AA -> 15/100 = .15
Aa -> 25/100 = .25
aa -> 60/100 = .60
if p^2 = AA = .15 then A = √.15 = 0.38729833462 = .39
if q^2 = aa = .60 then a = √.60 = 0.77459666924 = .77

Explanation:
Carbon dioxide is needed for photosynthesis, but oxygen is needed for cellular respiration. Assuming there is still oxygen then the plants will produce carbon dioxide and some of it will be reabsorbed by photosynthesis during daylight. However, ultimately there wouldn’t be enough carbon dioxide for the plants to grow and they will start to die. Some plants have evolved a C4C4 photosynthesis pathway so they only require a small amount of CO2CO2 to survive, however they do still require more than zero CO2CO2.
So basically you killed off all the plants and all the other non-microbial life died of starvation shortly afterward.

Composting is a form of waste that uses organic materials to put into plants in order to help them grow and flourish. It saves energy, and it doesn't give off many gasses to help the Earth. 
However, it is ineffective on the large scale and cannot be mass produced to help Earth instantly because of the large amounts of inorganic materials.
