Question

Two opposite forces operate in growth and development of every population. One of them has ability to reproduces at a given rate. The opposing force is

• A. Morbidity
• B. Fecundity
• C. Biotic potenital
• D. Environmental resistance

Answer 1

Answer: (D)

Environmental resistance

• The biotic potential is the rate at which a species reproduces with unlimited conditions. Biotic potential describes the number of offspring a species can produce when they have ideal circumstances, including unlimited food and water, safe habitat, and any other conditions that would promote successful reproduction.
• Environmental resistance is factors, that can limit the increase in a population. Common factors include predators, disease, competitors, and lack of food, water, and suitable habitat. Due to factors that contribute to environmental resistance, not all individuals that are born can survive to adulthood or reproductive age. As a result, the overall population of the species does not grow uncontrollably but instead is limited and controlled.
• All limiting factors in the environment that act on a particular population is termed as environmental resistance.
• Hence the opposing force is environmental resistance.
• So, the correct answer is 'Environmental resistance'.
