From the diagram above the optimal temperature for breeding cockroaches is
15oC
19oC
24oC
33oC
Maelezo
Optimal temperature refers to the temperature range at which a biological system, like an enzyme or organism, functions most efficiently. From the graph, the optimal temperature is the highest temperature peak of the curve where the number of cockroaches is highest. Consequently, it is 24\(^0\)C.
