Explanation:

aquatic components are of two types-

freshwater ecosystem( lakes and ponds, river and streams)

marine ecosystem(ocean ecosysyem, estuaries)

planktons-

planktons are found in limnetic zone, availability of sunlight is much here. planktons  are zooplanktons and phytoplanktons  are very important link in aquatic ecosystem.

sponges

In marine water, the <em>benthic zone</em> is the area below the<em> pelagic zone.</em> Here temperature decreased because of less light perception. This zone is very nutrient rich so organisms which are present here are- bacteria, fungi, sea anemone, sponges and some fishes.

The height of a column of mercury in a closed-end manometer is 13.2 cm. What is the pressure of the gas in torr
AlladinOne [14]

Answer:

P_{gas}=131.96torr

Explanation:

Helo,

In this case, the pressure must be computed as follows:

P_{gas}=gh\rho _{Hg}

Which is using the density of mercury (13.6 g/mL) and its height, thus, we obtain (using the proper units):

P_{gas}=9.8\frac{m}{s^2}*(13.2cm *\frac{1m}{100cm} )*(13.6\frac{g}{cm^3}*\frac{1kg}{1000g}*\frac{1x10^6cm^3}{1m^3} )\\\\P_{gas}=17592.96Pa*\frac{760torr}{101325Pa} \\\\P_{gas}=131.96torr

Best regards.
