Question

Populations evolve to maximise their reproductive fitness in the habitat in which they live. Study the population growth curves shown in the given graph and answer the questions that follow: \begin{figure}[h!] \centering \includegraphics[width=0.5\linewidth]{image.png} % Replace with the correct path to your image \caption{Population Growth Curves} \label{fig:populationgrowth} \end{figure} (a) Identify the growth curves \u2018A\u2019 and \u2018B\u2019.

Hint:

Exponential growth cannot sustain indefinitely due to limited resources, whereas logistic growth reflects realworld ecological scenarios.

Answer 1

Curve \u2018A\u2019: Exponential growth curve. Curve \u2018B\u2019: Logistic growth curve. Explanation: Exponential growth occurs under unlimited resources, showing a Jshaped curve. Logistic growth accounts for environmental constraints and levels off at the carrying capacity (K), forming an Sshaped curve.
