Question

10 multiple choice 1 point which of the following describes matter and energy flow in an ecosystem? matter and energy both cycle within an ecosystem. matter and energy flow in opposite directions within an ecosystem. energy flows through an ecosystem, whereas matter is recycled within an ecosystem. matter flows through an ecosystem, whereas energy is recycled within an ecosystem. matter and energy both flow through an ecosystem. clear my selection

Explanation:

To solve this, we recall ecological principles: Energy in an ecosystem is a one - way flow (from producers to consumers, lost as heat), while matter (like carbon, nitrogen, water) is recycled through biogeochemical cycles within the ecosystem.

• Option 1: Energy does not cycle, so this is wrong.
• Option 2: Matter is recycled and energy flows, they don't flow in opposite directions in the way described, so this is wrong.
• Option 3: This matches the principles (energy flows, matter is recycled), so this is correct.
• Option 4: Energy is not recycled, matter is recycled, so this is wrong.
• Option 5: Matter is recycled, not flowing through like energy, so this is wrong.

Answer:

C. Energy flows through an ecosystem, whereas matter is recycled within an ecosystem.
