The adaptation that is genetic change or mutatiton help makes an organism to survive better in their new environment.
Internal energy of the system changes by ΔE = 178 J.
Heat given to the system = Q = +658 J.
According to the first law of thermodynamics,
ΔE = Q + W
178 = 658 + W
∴ W = 178-658 = -480 J
Minus sign indicates that work is done by the system.
The more arms it has the less of a chance the prey has to swim away.
