Photosynthetic life existing on a planet farther from the Sun than the Earth would most likely be
A) smaller, less efficient at collecting solar radiation or have a faster metabolism than photosynthetic life on Earth
B) identical to photosynthetic life on Earth
C) larger, more efficient at collecting solar radiation or have a slower metabolism than photosynthetic life on Earth
D) impossible

Question

Quizplus · Accepted Answer

Photosynthetic life on a planet farther from the Sun than Earth would likely adapt to the reduced solar energy by evolving to be larger or more efficient at collecting solar radiation, or by having a slower metabolism to conserve energy. This adaptation would help maximize the use of available light for photosynthesis.
