The determination of seawater density, and its variation, is therefore one of the most important tasks in oceanography. How do you think the density of sea water changes with water depth? The density of sea water depends on: temperature T, salinity S and ; pressure P, which increases with water depth. Oceanographers discuss the density of sea water somewhat differently than a chemist or physicist. The values of sea water density, labeled on the diagonal lines in the graph below, do not include the density of fresh water (1 gram per cubic centimeter g/cm 3) or the decimal places.
Woodpeckers eat nuts, berries, termites, grubs, and other bugs that live inside trees. It pecks through the wood of a tree to find the bugs living inside. That is why their beaks are so long... and strong! + 66 others found this useful.
Symbiotic relationships in nature are ones in which two organisms benefit each other's survival. There are many examples that can be given, but one of the most interesting is the Rufous woodpecker of India and Sri Lanka (formerly Ceylon) and the black tree ant.The main diet of the Rufous woodpecker is black tree ants.One of the main items in the diet of the black tree ants is bird eggs. In the spring of the year when the woodpeckers get ready to lay their eggs, they will find a nest of the black tree ant and put their nest in the ant's nest.he main diet of the Rufous woodpecker is black tree ants.
