This example reflects the food chain.
<span>The food chain describes relationships among the organisms by showing how the organisms are related to each other by the food they eat. The food chain contains levels and each of them presents a different trophic level (position of the organism in that chain). There is reliable energy transfer through each stage of the chain. Not all the energy at one stage is absorbed by the organism at the next stage but, the amount of energy from one stage to another decreases.</span>
Answer:
This is in order to maintain the species number of chromosomes.
Explanation:
Reduction division occurs by meiosis and it is very necessary in organisms that reproduce sexually.
Meiosis will take place in the ovary and testis to produce haploid gametes that have half the number of chromosomes compared to the parent cell .
During fertilization the two gametes will fuse to form the offspring an offspring with the same number of chromosomes as the parent. The species number of chromosome has been maintained.
Without meiosis or reduction division the off-springs would have double the chromosomes as the previous generation did.
The new DNA molecule is identical to the original DNA.
DNA is replicated through a process called semiconservative replication. The two strands are separated and an enzyme called DNA-polymerase replaces the nitrogenous base for each strand resulting in two identical DNA molecules.

Digestion occurs when food is moved through the digestive system. It begins in the mouth and ends in the small intestine. The final products of digestion are absorbed from the digestive tract, primarily in the small intestine.
