为什么说在无机环境和生物群落之间信息传递？
（1）无机环境中的碳元素主要通过绿色植物的光合作用进入生物群落，还可以通过硝化细菌等的化能合成作用进入生物群落；生物群落中的碳元素主要通过动植物和微生物的呼吸作用返回无机环境
环境污染对动物有哪些影响？
你好，我是【不否答题】，很高兴为你解答。会造成动物的灭绝,会使动物的生存环境减少,使得该种动物种大规模迁徙.环境的某些污染(如核污染)会使动物基因突变,使物种的变异速度加快.更多专业的科普知识，欢迎关注我。如果喜欢我的回答，也请给我赞或转发，你们的鼓励，是支持我写下去的动力，谢谢大家。
求一份保护环境的ppt
There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.
To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.
In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.
保护环境
目前环保还存在着许多问题。最严重的问题就是空气、水和土壤的严重污染。污染的空气对人类的健康十分有害。污染的水引起疼病，造成死亡。更有甚者，随着现代社会的迅速扩建，植被大大的减少。
为了保护环境，各国政府做了大量的工作。采用了立法措施控制大气污染，保护森林资源和海洋资源，制止任何环境污染。因此，在当今的环保中政府起着最重要的作用。
我的看法是，为了保护环境，政府应当采取更具体的措施。首先，应当通过教育的方法使人们充分謒到环境保护的重要性。第二，应更加努力把计划生育政策付诸实施，因为人口多就意味着污染严重。最后，要严惩那些故意破坏环境者。使他们破坏环境就是毁灭人类自己。
