I think the end of the question is "g" not "c". To get the offspring wanted, there are two types of genotype, one is TTgg, the other one is Ttgg. The chance of getting TT or Tt is 1-(1/2)*(1/2)=3/4. The chance of getting gg is (1/2)*(1/2)=1/4. So the total chance is (3/4)*(1/4)=3/16.
a lack of resources would most likely decrease a population size because it will limit growth and decrease survival rates. There will also be more competition.
If a plant just did photosynthesis then the plant would not have any food and just an abundant amount of ATP. they use cellular respiration to make food they can use to grow
