| When a carnivorous plant catches an insect, the leaves serve as the stomach that digests it. Parts of or all of the trapped animal is broken down into a liquid by the leaves' special bacteria or digestive juices. This mixture of proteins, minerals and digestive juices is called a 'broth' or soup. The plant's leaves take in all the nutrients necessary for growth from the dead animal. |  |

Fog and Its Influence on the Water Relations of Coast Redwood

Understanding redwood water relations and forest health
Coast redwood trees inhabit a region of western North America that experiences cool fogs during most of the summer growing season. In recent years, studies have demonstrated the importance of fog water to the water relations of redwood forests. It has now been shown that all of the plants which inhabit redwood forests use fog to various extents, and that this unique water source is particularly important for young redwood saplings and many understorey species, especially in years of below-normal rainfall. Scientists from the University of California, Berkeley, U.S.A., aim to extend previous work by investigating the role of redwood canopies in the direct uptake of fog moisture.
