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.
Oxpeckers do eat ticks, but often the ticks have already fed on the ungulate host and no statistically significant link has been shown between oxpecker presence and reduced ectoparasite load. Oxpeckers have been observed to open new wounds and enhance existing ones in order to drink the blood of their perches.
