这是一篇图表类阅读题。此类短文通常只有少量的文字表述，要求考生依据所提供的图表或描述进行理解。阅读时必须弄清图表中各部件的对应关系，同时针对所设问题进行有目的的识读。
通过观察此图和图中的文字说明，我们可以得知这是一个“自然界中能源消耗流程图”。
1.整体识图题，根据图示和文字说明中的“Energy flows through the system…”一句可得。
2.细节判断题，根据文字说明“Significance of photosynthesis: it produces food, fuel, fiber and oxygen.”和普通常识可得。
3.细节识图题，此是要弄清图中各部件的对应关系，从“流程”图分析，首先植物接收太阳能，继而为草食动物提供食物，草食动物以为人和肉食动物提供食物，最后都化为腐烂物，为微生物提供食物。认清了这一内在关系，此题的答案就显而易见了。
4.逻辑推理题，从文字说明和图示表面很难找到答案，抓住所设问题中的“…in order to improve the living conditions…”关键词，结合图示下面的粗标题进行分析，树是“producers”，植树多，food, fuel, fiber and oxygen就多，当然生存条件就会更好。
