Answer:
Quadrat method is used for estimating the number of individuals in an area. In this method, a large square area on the ground or water surface is marked, call it an enclave. The number of animals present in this enclave is counted. Then by assuming that the animals are less migratory and are uniformly distributed, their number for a large area is estimated by the use of unitary method of calculation. Example a 4 square feet area has 2 snails, then a 1000 square feet area will have (1000 x 2)/4, i.e, 500 snails in it. Fishes can be counted using this method only if they are confined in a small water body like a lake or a pond. Rivers are flowing so the fishes may move along its length which can give us an underestimate or an overestimate of their numbers. Sea has its depth and huge area, and fishes can be moving randomly in it. Hence this method will not work for river and sea fishes.

Benedict's test can be used to test for simple carbohydrates. This test allows to identify reducing sugar. This sugars have ketones and aldehyde functional groups. This test can also be used to identify presence of sugar in urine. The red brick reaction of test is caused by the reducing property of simple carbohydrates. The copper ions in Benedict's solution are reduced to Coppe (I) ions resulting in change in color.
