Organisms leave a population when they migrate to another area in search of resources, experience a decrease in the availability of food or habitat, or face increased competition or predation pressures within the population.
if the snake population decreases (meaning there are less of them) the rabbit population will increases (meaning there are more of them) all do to the rabbits not being consumed by the snakes.
No, the population cannot increase and decrease at the same time in the same area. The population can either grow through factors like births, immigration, and decreased mortality rates or decrease due to factors like deaths, emigration, and natural disasters.
Population change refers to any increase or decrease in the size of a population, whereas population growth specifically refers to the overall increase in the population size over a given period, often expressed as a percentage. Population change can be influenced by factors such as births, deaths, immigration, and emigration, while population growth focuses on the net increase in population size resulting from these factors.
An uncontrolled grass carp population in a lake environment could disrupt the energy pyramid by consuming excessive amounts of aquatic vegetation, leading to a decrease in plant productivity. This could impact herbivores dependent on the vegetation for food, causing a decline in their population size. With fewer herbivores, the predators that rely on them for energy could also experience a decrease in abundance.

The percentage of the population from age 16 to 65 decreases.
The percentage of decrease from 421 to 293 is about 30.4%.
~65.385% is the decrease of percentage from 26 to 9.
percentage of decrease = amount of decrease divided b the original amount and then multiply.
The percentage decrease from 140 to 80 would be -42.8%
It is a 61% decrease
It is a 15% decrease
20% decrease.
This is a 35.9% decrease.
It is a 22.5806% decrease.
This is a 41.7808% decrease.
