Answer:
2n to n, n to 2n
Explanation:
Meiosis is known as reductional division because in meiosis the chromosome number gets reduced to half in daughter cells so when sperm and egg cells undergo meiosis than the chromosome numbers get reduced from 2n to n. In humans, the chromosome number is 46 and it gets reduced to 23 after meiosis.
When egg is fertilized by the sperm than the two chromosomes comes in the same cell and the number goes from n to 2n that mean in human it goes from 23 to 46.

Explanation: The number tertiary consumers will be less than the number of secondary consumers because as we move up in the ecological pyramid, the energy decreases.
The largest number of organism having the greatest amount of energy are producers.
They transfer only 10 per cent of the total energy they have. The primary consumers transfer only 10 per cent of the total energy they have to consumers.
The number of organism decreases along with increase in the tropic level of energy pyramid.
