3. Graph of data from Hone Your Problem Solving Skills (Ch. 11, p. 268) 0.6- 0.5 bor d (/individual/year) 0.2 150 250 100 Density (#/square m) Based on graph above answer the following questions: Birth rate (b) is (density-independent or density-dependent). Death rate (d) is (density-independent or density-dependent). The population would be when density is 200/m2 The population would be when density is 150/m2. The population would be when density is 100/m2 The population would be when density is 500/m2 (increasing, decreasing, not changing or cannot determine) The carrying capacity (K) would be

Answer 1

birth rate (B) is a density-dependent

death rate (d) is a density-independent

The population would be decreasing when density is 200/m² .since the death rate is more than the birthrate.

The population would be increased when density is 150/m² ..since the birthrate is more than the death rate.

The population would be increased when density is 100/m² ..since the birthrate is more than the death rate.

The population cannot determine when density is 500/m² .since the graph does not give the details for density 500/m². if the nature of the graph is similar as the density increases we can say the population is decreasing.

the carrying capacity would be 125/m²
