Detailed explanation-1: -These density-independent factors include food or nutrient limitation, pollutants in the environment, and climate extremes, including seasonal cycles such as monsoons. In addition, catastrophic factors can also impact population growth, such as fires and hurricanes.
Detailed explanation-2: -Introduction: Population ecology studies the density, distribution, size, sex ration, and age structure of populations.
Detailed explanation-3: -For organisms that move around, such as mammals, birds, or fish, a technique called the mark-recapture method is often used to determine population size. This method involves capturing a sample of animals and marking them in some way-for instance, using tags, bands, paint, or other body markings, as shown below.
