• C. 1-3-2-4
• D. 4-3-2-1

Answer 1

The correct option is C 1-3-2-4

All organisms want to reproduce to ensure species propagation. This usually leads to an increase in their population. Also, every individual organism is different from another. This phenomenon is called variation. There is variation at all levels of ecosystem. This variation gives different species with different capabilities to adjust with the environment. As the population increases, the competition for resources which are limited also increases. Nature acts as a referee in this competition. It sets different rules and conditions and all other players (species) adjust accordingly. Ultimately nature selects the best. The species which survive the test evolve with time and eventually develop into new species. This is called survival of the fittest.
