It gets smaller because the number of animals dying is greater than the number of animals being produced.
No. It would be true if there were no immigration. Also, there may be cycles: times when the death rates are greater than birth rates so that the population gets smaller, and other periods when the opposite happens. If you are interested, read about population cycles of crickets, for example.
It depends on the animal in question. A viable population will ensure that there are enough individuals to ensure the population will remain in a viable condition for a given period of time. Some scientists hold to the belief that a minimum viable population of 50-500 individuals will ensure the sustainment of the population over time.
The population of the golden-bellied capuchin monkey is about 300 individuals - this animal is critically endangered.
yeah the animal population is outnumbered about 4 to 1 :)
Wild animals will often kill an individual animal that looks different from the rest of them.
Yes, animal cells do contain vacuoles, smaller than those found in plant cells but greater in number. Some animal cells do not however, have any vacuoles.
A dogs pulse is greater than a humans. The smaller the animal the faster the heartbeat. For example if you compare a cat to a mouse, the mouse has the faster heartbeat because of its size.
an animal population is group of the same species
Animal Cells Are Smaller than Plant Cells
Animal - clothing -'s population is 2,004.
A natural cause of decline in a population could be disease outbreak or an epidemic. Diseases can spread rapidly through a population, resulting in a significant decrease in the number of individuals. This decline in population can occur in both plants and animal species.
