Answer:
This will lead to an  decreases  in the ATPs synthesis. This is because low pH , high acidity favours ATP synthesis, because it increases the  proton concentration for electrochemical gradients needed for energy that  ATPase enzymes makes used of   synthesis  of ATPs.
Therefore a rise in the pH(low acidity) lowers protons levels, and therefore reduced electrochemical gradients , with a drop in energy for ATPs synthesis.

Answer: Option A 
Explanation:
Birds attach the bur of the plant which helps in the pollination. The birds sit on the plant and the burs of the plant gets attached in the legs of the birds which is transferred from one place to another.
Seeds at a different place will help in reproduction and growth of the plants. In this case the birds are carrier of the burs.
This is how the birds help in the reproduction of the plants by becoming the messenger.
