The Verhulst-Pearl logistic growth model represents population growth with a limiting factor, \( K \), which is the carrying capacity of the environment.
- \( r \) represents the intrinsic rate of natural increase.
\[ \begin{array}{|c|c|} \hline \textbf{Symbol} & \textbf{Meaning} \\ \hline K & \text{Carrying Capacity (Maximum population size)} \\ r & \text{Intrinsic Rate of Natural Increase} \\ \hline \end{array} \]
- \( K \) is the maximum population size that the environment can sustain indefinitely, taking into account resource limitations.
Thus, the correct answer is (3) Carrying capacity.
Study the pie chart given below, representing the global biodiversity and proportionate number of species of major taxa.
Answer the following questions:
[a] Identify 'X' and 'Y' in the given pie chart.
[b] Which one of the two 'X' or 'Y' is the most species-rich taxonomic group and by what percentage?
[c] Name the level of Biodiversity represented by the following:
List I | List II | ||
A | Down’s syndrome | I | 11th chormosome |
B | α-Thalassemia | II | ‘X’ chromosome |
C | β-Thalassemia | III | 21st chromosome |
D | Klinefelter’s syndrome | IV | 16th chromosome |
