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.
It is called facilitated diffusion which is a type of passive transport.
The answer is c hope this helped
Answer:
Rate of photosynthesis will be increased
Explanation:
Photosynthesis is a process whereby plants manufacture their food (in form of carbohydrates) in the presence of sunlight. The photosynthetic process, which occurs in the chloroplast of plant cells, require carbon dioxide (CO2) as one of the reactants, from the atmosphere. The general photosynthetic equation is given below:
6CO2 + 6H2O → C6H12O6 + 6O2
Based on the above equation, it shows that carbon dioxide (CO2) as a reactant can either increase or decrease the rate at which photosynthesis in plants occur depending on whether it is increased or decreased in the atmosphere respectively.
According to this question, the concentration of carbon dioxide in the atmosphere has been increasing for many years. This means that the rate at which photosynthesis by plants occur will also be INCREASED.
