populations of animals

The average annual rate of decrease in the population of a rare animal group is 4.5%. The initial population of the group is 2600. If the rate continues, estimate the population after 11 years. => 117 or 2483 or 1568 or 236..

Population Control - Increasing population is a serious issue, particularly in developing countries. It is necessary for every generation to produce more off springs because many individuals do not survive to reach the reproductive age due to natural causes. However, man has ups..

It is the total number of individuals of a species per unit area or volume at a given time. (Such as number of animals per square kilometre or number of trees per area etc.) Population density reflects the success of a species in any given area. Population density (P...

Although population of some animals is also studied, the population of human beings is most extensively studied. Whenever the word population is used, it connotes the human population. Population is one of the most important subjects..

All animal species, which are domesticated and grow friendly to human beings, are grouped as animal resources. These are some select species of animals. But they are large populations of each species, while wild species are large in number with smaller ..

Acid rain chemically strips waterways of necessary nutrients and lowers the pH to levels where plants and animals cannot live. Most of the aquatic animals cannot survive when the pH is less than 4. Some species of fish, such as salmon, die even when the pH is less than 5.5. Cer..

Suppose that the animal population in a forest is 200 initially, its birth rate is k P, where k is a constant and death rate is 0.03P. What is the value of k , if P′(0) = 400? [P = P( t ) is the animal population after t years.] => 0.04 or 0.4 or 0.002 ..

.e., their shelter, control of disease and proper utilization of their products. The various animal food resources that provide food are livestock, poultry and fish. Food is one of the basic needs of man. Early man lived on roots and berries of wild plants but with civilization, man learn..
