Answer:
Main Difference – Mutation vs Variation
Mutation and variation are two simultaneous events involved in the process of evolution. The main difference between mutation and variation is that mutation is an alteration in the nucleotide sequence of a gene whereas variation is any difference between individuals of a particular species. Mutations may arise due to environmental factors such as chemicals and UV. Germline mutations are inherited by the offspring. Somatic mutations occur in the ordinary body cells. Variation can occur due to mutations, genetic recombination, gene flow, genetic drift, random mating, random fertilization, and environmental factors. Variation may also cause evolution through natural selection.
Primary succession is the colonization of living organisms into an area that was not previously colonized by any living things. A Secondary succession is the regeneration of the living community after a major disturbance.

The process by which large undissolved particles are brought into a cell being engulfed is known as phagocytosis. Phagocytosis is the process by which certain living cells called phagocytes ingest or engulf other cells or particles. The phagocyte may be a free-living one celled organisms, such as an amoeba, or one of the body cells, such as white blood cell.
