In ecosystems, energy and matter have distinct patterns of movement. The correct description is:
**Energy flows in one direction, and matter cycles through the environment.**
Energy enters ecosystems primarily from the sun, is captured by producers (like plants) through photosynthesis, and is then transferred through various trophic levels (herbivores and carnivores) as it moves through food chains. However, energy is eventually lost as heat and cannot be reused by the ecosystem.
On the other hand, matter (such as nutrients) cycles through the ecosystem. It is recycled through various biological processes, including consumption, decomposition, and nutrient uptake by plants, making it available across different levels of the food web. Therefore, while energy flows in a one-way direction, matter continuously cycles within the ecosystem.
