A population of ground squirrels has an annual per capita birth rate of 0.06 and an annual per capita death rate of 0.02. Using these birth and death rates, calculate an estimate of the total number of individuals added to (or lost from) a population of 1,000 individuals in one year.

40 squirrels are being added to the population per annum

Explanation:

The death rate is 0.02 per capita per annum, and the birth rate is 0.06. If the population size is 1000, the number of deaths per annum = 1000* 0.02 = 20. The number of births per annum = 1000* 0.06 = 60. Thus, total 40 numbers of squirrels are being added to the population per annum.

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
