- a)a gradual decrease in the species diversity
- b)a gradual increase in the ecosystem diversity
- c)a gradual increase in the species diversity
- d)no change in the species diversity
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
When we will move away from the equator towards poles, we will find:a)...
When we will move away from the equator towards poles there is a gradual decrease in the species diversity. This is because climatic condition becomes gradually adverse as we move from equator to poles.

Decrease in Species Diversity towards Poles
Heading: Introduction
Moving away from the equator towards the poles, we experience a change in temperature, amount of sunlight, and precipitation. These changes significantly impact the distribution of various species and their diversity.
Heading: Factors Affecting Species Diversity
1. Temperature
As we move towards the poles, the temperature decreases. This decrease in temperature affects the metabolism of many species making it difficult for them to survive. Many species become inactive or dormant during the winter season to conserve energy. This decreases the number of species present in the region.
2. Sunlight
The amount of sunlight decreases towards the poles. Many species require sunlight for photosynthesis, and the reduction in sunlight limits their growth and survival. Also, the availability of sunlight directly affects the productivity of the ecosystem.
3. Precipitation
The amount of precipitation decreases towards the poles. Many species require a certain amount of water to survive. The decrease in the amount of precipitation limits the growth and survival of many species.
Heading: Effect of Decrease in Species Diversity
The decrease in species diversity towards the poles has a significant impact on the ecosystem. The following are the effects:
1. Reduced Productivity
The productivity of the ecosystem decreases as the number of species decreases. Fewer species means less competition, but at the same time, it also means less cooperation. Many species work together to increase the productivity of the ecosystem.
2. Reduced Resilience
The resilience of the ecosystem decreases as the number of species decreases. The ecosystem becomes more vulnerable to environmental changes, and it becomes difficult for the ecosystem to recover from disturbances.
Conclusion
In conclusion, as we move away from the equator towards the poles, we experience a gradual decrease in the species diversity. The decrease in species diversity has a significant impact on the productivity and resilience of the ecosystem.
