Answers
Answer:
It is true that the 'Modifications made to the environment to reduce the impact of limiting factors can cause disruption to the natural balance of an ecosystem'.
Explanation:
Option (a) is true. Ecological imbalance occurs when changes are made to the natural environment in order to minimize the impact of limiting factors.
Option (b) is not true, as human beings keep on modifying the environment for adaptive living, such as constructing new building and deforestation.
Option (c) is not true, as it is not possible to completely overcome the ecological factors that reduce the size of population. Eg. Human cannot stop storm, earthquake, etc.,
Option (d) is not true. Human population is directly dependent on limiting factors. Eg. When space to live increases, human population increases.
Answer:
It is true that the 'Modifications made to the environment to reduce the impact of limiting factors can cause disruption to the natural balance of an ecosystem'.
Option (a) is true. Ecological imbalance occurs when changes are made to the natural environment so that the impact of limiting factors is minimized. The other options are not true. Only Option A is true.
