Q26 of 50 Page 1

Study the graph given below and answer the questions that follow :


(i) Write the status of food and space in the curves (a) and (b).


(ii) In the absence of predators, which one of the two curves would appropriately depict the prey population?


(iii) Time has been shown on X-axis and there is a parallel dotted line above it. Give the significance of this dotted line.


1.)Status of food and space in curves are-


a) When the resources are unlimited, the curve is exponential. There are limiting food and space for the population depicted by curve


b) When the resources are limiting, the curve become sigmoid.


2.) In the absence of predator curve (a) would appropriately depict the prey population because when there is no predator, then population would exponentially increases.


3.) The dotted line shows the carrying capacity of the environment which represents the size of population that environment hold with the present resources
