Question

In 3-5 sentences, compare and contrast the flow of matter and energy for land-based ecosystems and marine ecosystems. How and why are they similar, and how and why are they different?

Answer 1

Both land-based ecosystems and marine ecosystems involve the flow of matter and energy through food webs, but there are some key differences. In land-based ecosystems, photosynthesis is the primary source of energy, while in marine ecosystems, energy primarily comes from the decomposition of organic matter. Both ecosystems cycle nutrients through the food web, but the types of nutrients and the mechanisms of cycling differ due to different geological and physical characteristics. Overall, the similarities lie in the flow of matter and energy, while the differences arise from the distinct environmental conditions and adaptations required in each ecosystem.
