Consider the following data. rates for cheetah population from 2011 to 2012 cause of change 2011 2012 deaths 2 1 births 5 4 immigration 6 1 emigration 8 3 which would have to happen to make the population growth of cheetahs in 2013 equal to the population growth observed in 2011 and 2012? a) 4 deaths, 7 births, 2 immigration, 6 emigration b) 3 deaths, 6 births, 5 immigration, 7 emigration c) 5 deaths, 2 births, 8 immigration, 3 emigration d) 1 deaths, 5 births, 3 immigration, 7 emigration

The correct answer would be B) 3 deaths, 6 births, 5 immigration, 7 emigration.

Population density of an area in a specified time can be calculated with the help of formula N = (B + I) – (D + E), where,

Thus, the population density in 2011 would be = (5 + 6) - (2 + 8) = 1.

Similarly, in 2012 the population density would be = (4 + 1) - (1 + 3) = 1.

Population density according to data provided in option B = (6 + 5) - (3 + 7) = 1.

Thus, correct answer would be option B

b on edge

Explanation:

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
