Primary consumers (such as grazers and browsers) of the biological community will put pressure on the primary producers (these are plants) since the primary producers have limited resources (water) to reproduce due to the drought. The primary producers hence become scarce and cause the primary consumers to compete for limited resources. This causes the primary producers to reduce in population. Reduction in their population causes limited resources for secondary consumers and this cascades up the food web to tertiary consumers.

Answer: The genotype of the child is aa
Explanation:
Both parents are normally pigmented but the child has albinism. We know that albinism is a recessive trait. 
This tells us that the parents were heterozygous for albinism (Aa)
Each parent carried the recessive allele for albinism and passed it down to their child.
The parents are normally pigmented because the dominant allele (normal) masked the recessive albinism allele.
