| As CO2 becomes more available, other things being equal, they will photosynthesise more. |
| The weeds photosynthesise by releasing oxygen into the water during the day and taking it back in at night. |
| When the fruit ripen, the plant turns greenish and obtains the ability to photosynthesise. |
| Each bit of debris was, in effect, a tiny ecosystem. As with many ecosystems, the bottom of the food chain was occupied by things that photosynthesise. |
| This means that even during the Arctic winter, some algae can continue to photosynthesise using the very weak light of the polar night. |
| The minuscule zooplankton feed on ocean algae which, like all plants, use carbon dioxide to photosynthesise. |
