　　TOEFL托福阅读真题文章：

　　The term "ecosystem" refers to the complex web of interactions between living organisms and their physical environment. Ecosystems can range from small, localized communities like a pond or a forest clearing to vast, global systems like the Amazon rainforest or the world’s oceans. Each ecosystem is characterized by its unique set of species, climate, and geological features, all of which interact in intricate ways. For example, plants in a forest absorb sunlight, water, and carbon dioxide to produce energy through photosynthesis. This process not only sustains the plants themselves but also provides oxygen and food for other organisms, such as animals and fungi. Meanwhile, decomposers like bacteria and fungi break down dead organic matter, recycling nutrients back into the soil for plants to use again.
