来 今日另发一篇介绍Ecosystem Ecology 的文，读的开心~
What powers life？How do sunlight and nutrients affect the plants we depend on？How do greenhouse gases and other contaminants degrade the interactions among the plant, animal, and microbial populations that comprise ecosystems？
Understanding how ecosystems work begins with an understanding of how sunlight is converted into usable energy, the importance of nutrient cycling, and the impact mankind has on environment. Plants convert sunlight into usable forms of energy that are carbon based. Primary and secondary production in populations can be used to determine energy flow in ecosystems.Studying the effects of atmospheric？CO2 will have future implications for agricultural production and food quality.
