Ecologists have found that
A)life as we know it does not match the energy laws of physics.
B)ecology cannot be explained using principles from chemistry and physics.
C)it is possible to capture all the photosynthetic energy absorbed in a molecule of glucose.
D)energy flows one way through an ecosystem and requires an external input.
E)inorganic elements flow through an ecosystem.

Question

Quizplus · Accepted Answer

The concept of energy flow through ecosystems is a fundamental principle in ecology. This principle states that energy cannot be recycled and flows one way through an ecosystem, requiring an external input (usually from the sun) to continue powering the ecosystem's processes. This is why choice D is the correct answer. Choices A and B are incorrect because life as we know it does match the energy laws of physics, and ecology can be explained using principles from chemistry and physics. Choice C is also incorrect because it is not possible to capture all the photosynthetic energy absorbed in a molecule of glucose - some of this energy is lost as heat. Choice E is incorrect because inorganic elements do cycle through ecosystems, but this is not the same as energy flow.
