Answer:
B, producers make glucose and oxygen for consumers to use during cellular respiration.

Answer:
True, the identification and location of genes and their effect has been difficult because of the phenomenon of epistasis.
Explanation:
Epistasis happens when the effect of a gene (locus) depends on one or more genes being present, that is. When epistatic mutations occur, they have different effects when they are in combination with when they are not. It occurs due to interactions between or within genes, which leads to unpredictable effects.
