A population growing in a habitat with limited resources shows four phases of growth in the following sequence.
- Acceleration - Deceleration - Lag phase - Asymptote
- Asymptote - Acceleration - Deceleration Lag phase
- Lag phase - Acceleration - Deceleration - Asymptote
- Acceleration - Lag phase - Deceleration -Asymptote
The Correct Option is C
Solution and Explanation
(i) Lag phase No or very little growth.
(ii) Acceleration Growth in the beginning.
(iii) Exponential phase Number of individual increases at an logarithmic rate.
(iv) Deceleration phase Rate of population increase slow down.
(v) Stationary phase Essentially no net change.

Organisms and Populations
Organisms:
An attached living system that lives in an environment is commonly known as an organism. These organisms are able to retain certain behaviors and structures. Some examples of organisms are plants, animals, bacteria, fungi, and humans. A group of these organisms leads to the formation of a population. The collection of the population forms a community that assists in the operation of ecosystems.
Each and every organism has the ability to adapt itself to various conditions of the environment. This capacity of organisms is due to their genetic variations. It is due to this only that their probability of survival get increases. For instance, camels adapt themselves to survive in desert areas and polar bears adapt to the extreme cold conditions or situations through their dense fur coat.
Populations:
A collection of organisms or individuals of a species that live, at a specific time, in a geographical area that is well-defined and capable of interbreeding is described as a population.
