80. Estuaries possess distinct blooms of excessive growth of a pigmented dinoflagellates. These blooms are called
(a) red tides      (b) sea tides     (c) black tides    (d) sea flowers

Ans: a

• Red tide is a common name for a phenomenon known as an algal bloom (large concentrations of aquatic microorganisms) when it is caused by a few species of dinoflagellates and the bloom takes on a red or brown color.
• Dinoflagellata are generally marine plankton, but they are common in fresh water habitats as well. Their populations are distributed depending on temperature, salinity, or depth. Many dinoflagellates are known to be photosynthetic, but a large fraction of these are in fact mixotrophic, combining photosynthesis with ingestion of prey. (A mixotroph or bitroph is an organism that can use a mix of different sources of energy and carbon, instead of having a single trophic mode on the continuum from complete heterotrophy at one end to autotrophy at the other.)

Ans:  a

• Subtropical Humid Climate (Cf) or China Type of Climate: The Humid Subtropical climate is found on the east coast of continents  between 20o and 40o north and south of the equator.Temperatures usually stay high (above 70) throughout the year, but cool down for a few months, so there are really only 2 seasons here: summer and winter.  However, the winter season is not a cold winter.  Summer season lasts longer, since Humid Subtropical areas are somewhat near the equator. Humid Subtropical climate is known for hot humid summers and mild winters.  Most Humid Subtropical areas receive about 120 cm of rain each year.  The rain falls throughout the year but summer has maximum rain. The regularly high temperatures evaporate water, which causes humidity and precipitation.  The high humidity in this region makes summer temperatures feel even hotter.  Humid Subtropical areas usually experience strong storms such as tornadoes and hurricanes.

(a) 40 years   (b) 45 years   (c) 50 years   (d) 60 years

Ans: d

• f = 3 d
• s = 0.5 m
• f – m = 9 => 3d – m = 9 —- (1)
• s – d = 7 => 0.5 m – d =7 —- (2)
• Solving (1) and (2), m = 60
