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? Write in short sentences.

Both land-based and marine ecosystems rely on the flow of matter and energy through food chains and food webs to sustain life. However, land-based ecosystems primarily involve terrestrial organisms and plants while marine ecosystems involve aquatic organisms. Both ecosystems transfer energy from one organism to another through consumption, but marine ecosystems may have more complex interactions due to the vastness of the ocean and the diverse range of species that inhabit it. Both ecosystems also play a crucial role in regulating the Earth's climate and supporting biodiversity, but land-based ecosystems may face more threats from habitat destruction and pollution due to human activities.
