The correct terms to fill in the blanks would be requires, releases and decrease, respectively. The synthesis of complex molecules requires energy, whereas their degradation releases energy. This synthesis occurs with a decrease in entropy. The synthesis of the complex molecules is an endothermic process where it requires supply of energy for the process to occur while the degradation is exothermic where it releases excess energy as the process proceeds. Synthesis of these molecules is accompanied by a decrease in entropy since the disorder in the system is lowered due to the bonding of two smaller molecules into one larger molecule.
Answer: The selective pressures(predators) in the environment acted more on the white moths than the black moths.Therefore there was a directional selection towards the black moths compare to the whites;with a shift in alleles frequency towards the black phenotype.
Conclusion: Black moths were naturally selected compare to the whites;as evident from 52 to 14 numbers recaptured
