Introduction:
Growth curve represents the population growth with each period of time. Growth curve can be demonstrated by two types of growth curve: J shaped growth curves and sigmoid growth curve. The J shaped growth curves represent the unrestricted or exponential population growth while sigmoid growth curve represents the slow or restricted growth of population.
Answer to Problem 1MC
Correct answer:
Density-independent environmental resistance includes floods. Therefore, option (b) is correct.
Option (b) is given as “floods”.
Explanation of Solution
Justify reason for the correct statement:
Density-independent factors are those factors that affect
Hence, option (b) is correct.
Justify reasons for the incorrect statements:
Option (a) is given as “predation”.
Predation is density dependent environmental resistance. Hence, it is a wrong answer.
Option (c) is given as “differentiated cell”.
Option (d) is given as “competition”.
Competition is density dependent environmental resistance. Hence, it is a wrong answer.
Hence, options (a), (c), and (d) are incorrect.
The factor floods are density independent environmental resistance.
