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 'A': Represents exponential growth. Curve 'B': Represents logistic growth. Explanation: Exponential growth, characterized by unlimited resources, follows a J-shaped trajectory. Logistic growth, however, acknowledges environmental limitations and plateaus at the carrying capacity (K), resulting in an S-shaped curve.
