Which group of organisms regulate their internal body temperature using their metabolism?
A
Endotherms
B
Phototrophs
C
Ectotherms
D
Halophiles
Verified step by step guidance1
Understand the key terms: Endotherms, Phototrophs, Ectotherms, and Halophiles. Endotherms are organisms that regulate their internal body temperature using metabolic processes. Phototrophs are organisms that obtain energy from light. Ectotherms rely on external environmental conditions to regulate their body temperature. Halophiles are organisms that thrive in high-salt environments.
Focus on the question: It asks which group regulates their internal body temperature using metabolism. This means the correct group must have the ability to generate heat internally through metabolic activity.
Eliminate incorrect options: Phototrophs and Halophiles are not related to temperature regulation. Ectotherms do not use metabolism to regulate their body temperature; they depend on external heat sources.
Identify the correct option: Endotherms are the only group that uses metabolic processes to maintain a stable internal body temperature, regardless of external conditions.
Conclude that the correct answer is 'Endotherms' based on the explanation and elimination of other options.
