The number and kinds of organisms is not constant. How do you explain this statement?
Answers (1)
Ans: First talking about the number of the organisms, the population of any species of organism is not constant. The population tends to change in accordance with the conditions. If the conditions are favourable, then the population grows else the population reduces. Next, the kinds of any organisms also do not remain constant because evolution is a never-ending process, and the variations in the species keep happening. The species that are able to adapt to the changing conditions survive, else the species become extinct. Also evolution leads to formation of new species.
