Population growth is the increase in the population number of a given species in a time. Longevity, migration and fertility rates affect population growth.
<h3>What are the factors affecting population growth?</h3>
<u>Increased Longevity</u> has impacted the population growth as the life expectancy has resulted in the accumulation of more people as their age of living has increased.
<u>International Migration</u> can affect the population growth positively and negatively as moving of the person from one region will decrease its population growth while the region where they go will have increased population.
<u>Fertility Rates</u> has a great impact on the population as the fertility rate had decreased due to many factors and the population has declined.
Therefore, option A. longevity option B. migration and option C. fertility rates influence the population growth.

<h2>Competitive exclusion </h2>
Explanation:
Competitive exclusion principle states that if two species compete for same resources then they cannot coexist together that is why Chthamalus is excluded by zones from Semibalanus balanoides
Zonation of barnacles is influenced by competition
Chthamalus not only occupy the mid-shore but survive and grow better than in its normal high-shore zone
Chthamalus is more tolerant of physical stresses than Semibalanus, and can therefore survive in the high-shore, where it has a ‘spatial refuge’ beyond the limits of Semibalanus
In the mid-shore, however, Semibalanus thrives and competitively excludes Chthamalus by undercutting or overgrowing it
The organ in which a fertilized ovum implants and develops into a baby is called the uterus
