How do the chromosome number remains the same in the members of same species?

We'll use humans as an example since it's simple and relevant.
All healthy humans have 46 chromosomes (23 pairs of very similar chromosomes). When gametes are formed in meiosis, this number is halved, such that sperm and ovum have only 23 chromosomes (just one of each pair). When these gametes meet and fuse as a result of sexual reproduction, the 23 chromosomes from the ovum and the 23 chromosomes from the sperm combine to form the full set of 46.
Sometimes meiosis doesn't quite work perfectly, though. Downs Syndrome is an example of this (one gamete has both copies of chromosome 21, so after fusion with the other gamete there are 3 chromosome 21s!).

Explain the statement: the energy for all organisms in a food web can be traced back to the son. Note: do not write “the sun is
AveGali [126]
The energy in all food webs and chains can, in fact, be traced back to the sun. The sun produces different types of electromagnetic energy waves, one of which is visible light. This type of energy cannot be used by most organisms; except for plants. They convert light energy into chemical energy via the process of photosynthesis. This chemical energy is now available to pass through the trophic levels of food chains.
