If we assume that population density is a good indicator of threat to the environment, which hotspots are not in particularly bad shape now, but are likely to become problematic in the future because their populations are currently growing quickly?

Expert Solution & Answer

Summary Introduction

To determine The hotspots, which are not in bad shape now but is likely to become problematic in the future due to the rapid increase in their populations.

Introduction: Population density is the measure of the total number of individuals per unit area. Population growth and size are regulated by different density-dependent and independent factors. These factors interact with each other to give various patterns of increase in population.

Explanation of Solution

The conservation of the hotspots or endemic species-rich areas is essential to protect the world’s biological heritage. The rapid increase in the human population leads to capturing the hotspot area where the endemic species exists because of the increasing birth and death rates of the human population along with the high immigration into these areas. The human migration in hotspots leads to habitat destruction.

In Madagascar, a total of 90 % of the original forest has already been lost. Another example is the forests of the Atlantic coast of Brazil, where the increasing rate of deforestation has led to the loss of 95% of the original forest. The hotspots where the population density is low today are Choco, tropical Andes, Madagascar, and Indian Ocean Islands. The hotspot with a high population growth rate is Brazilian Cerrado.

All organisms need nitrogen in order to grow and repair. Although nitrogen exists in its elemental form in the atmosphere, it cannot be directly used by plants. 7 Where else can plants obtain their nitrogen from? Plants make their own nitrogen. B Plants get it from animals. Plants get it from the soil. D Plants have special structures to break down atmospheric nitrogen. v3.7.63.140.4 | 6763e9417a3dbb80fa0f87b2 | Dec 19, 2024 | 3:07 PM | 84126 | en_8
