photosynthesis

It has at least one gene necessary for photosynthesis—so far it’s the only animal known with this ability..它有至少一个基因是光合作用所必需的——到目前为止这是唯一被发现具有此项能力的动物。

The belt of vegetation that crosses Africa below the Sahara is very dark because most of the sunlight is absorbed by plants for photosynthesis..在撒哈拉沙漠下方，横贯非洲中部的植被带颜色非常深，因为植物由于光合作用吸收了大多数太阳光。

As the ocean warms, it becomes more stratified, with the warmer water remaining at the top where the organisms need to be in order to do photosynthesis..但是随着海水变暖，它的层次会更加分明，温度更高的海水会停留在表面，而这里正是生物体进行光合作用必需的地方。
