Final answer:
The metabolic rate of poikilotherms roughly doubles for every 10°C rise in temperature due to increased enzymatic reactions, but this is beneficial only up to a point to avoid protein denaturation.
Step-by-step explanation:
The metabolic rate of poikilotherms roughly doubles for every 10°C rise in temperature. The correlation between temperature and metabolism in these organisms is due to the increased rate of enzymatic reactions that occur when temperatures rise. However, it's important to note that this increase in metabolic rate is generally beneficial up to a point, beyond which essential proteins and enzymes may begin to denature.
Homeostasis and thermoregulation are crucial for poikilotherms, as they rely on external sources to regulate their body temperature. These organisms adapt to temperature changes through various means, such as hibernation, aestivation, or migration, which helps them maintain a balance between their internal temperature and metabolic needs.
