Question

2. Refer to the equation below.



What do each of the two terms labeled as 1 and 2 represent in this equation? 1 = Effect of species A on growth rate of species B; 2 = Effect of species B on growth rate of species A 1 = Density-dependent growth rate of species A; 2 = Density-dependent growth rate of species B 1 = Effect of species A on growth rate of species B; 2 = Density-dependent growth rate of species B 1 = Density-dependent growth rate of species A; 2 = Effect of species B on growth rate of species A .) Y2

Explanation / Answer

1. Option 4 is correct wherein part 1 is density dependent growth rate as it concerns only with population of A while part 2 is telling about the effect of population B on growth of A.

2. Option 1 is correct. Population A has a negative affect on the growth of species B. they both A and B do not have cumulative effect on population growth.

3. Option 4 is correct. Species A has negative effect over B because in graph, the population of B has declined significantly and it continues to decline, while population B has inclination with continuation in growth. Therefore, laterally species B may extinct if the both species A and B reside together.

In the interspecific competition, only one species survives; the other goes extinct
