Question

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.

Answer 1

in absence of predators it's (a)
n the dotted line is k

Answer 2

Answer:

Explanation:

(i) There is sample food and space for the population, that is depicted by curve.

(a). When the resources are unlimited, the curve will be exponential. There is a limited food and space for the population that is depicted by the curve.

(b). Also, when the resources are limiting, then the curve becomes - sigmoid.

(ii) In the absence of predators, the curve (a) will appropriately depict the overall prey population.

(iii) The dotted line present in the chart, represents the overall carrying capacity of the environment. The carrying capacity represents the size of population which the environment can hold by providing  the necessary resources. Thus, when the population reaches this line, the mentioned population size is stabilised by many environmental factors.
