Greater Variety and Abundance of Life in a Region with 200 cm Annual Rainfall:

There are several reasons why a region that receives 200 centimeters of annual rainfall would have a greater variety and abundance of life compared to a region with only 5 centimeters of annual rainfall.

1. Water availability:
- A higher amount of rainfall provides abundant water resources, which is essential for the survival and growth of various organisms.
- With 200 centimeters of rainfall, the region would have more rivers, lakes, and ponds, providing habitats for aquatic organisms like fish, amphibians, and aquatic plants.
- The availability of water also supports the growth of vegetation, which in turn provides food and shelter for a wide range of terrestrial organisms.

2. Biodiversity:
- The increased availability of water in a region with 200 centimeters of rainfall creates a diverse array of habitats, including wetlands, forests, and grasslands.
- These varied habitats support a greater number of species, leading to higher biodiversity.
- The region would likely have a larger variety of plants, animals, and microorganisms, including both specialized species adapted to specific habitats and generalist species that can thrive in various environments.

3. Food Chain and Ecosystem Complexity:
- The abundance of water and diverse habitats in the region with 200 centimeters of rainfall supports complex food chains and ecological interactions.
- A wide variety of plants and insects serve as the primary producers and provide a food source for herbivores.
- The presence of herbivores, in turn, sustains populations of carnivores and omnivores, creating a more intricate and interconnected ecosystem.

4. Migration and Adaptation:
- The higher rainfall in the region provides opportunities for migration and adaptation.
- Various organisms, including birds and mammals, may migrate to the region during times of water abundance.
- The availability of water also allows for the colonization of specialized species that have adapted to life in aquatic environments.

Conclusion:
In summary, a region that receives 200 centimeters of annual rainfall is likely to have a greater variety and abundance of life compared to one with only 5 centimeters of rainfall. The availability of water resources, diverse habitats, increased biodiversity, complex food chains, and opportunities for migration and adaptation all contribute to the flourishing of life in regions with higher rainfall.

The region receiving annual rainfall more than 200 cm is more likely to have abundance of life because --
1) It maintains the annual weather conditions of a region.It helps to moderate the climatic conditions.
2)Tropical and temperate forests are abundant in these regions as growth of forests depends on rainfall.
3) Due to availability of water, agriculture is also abundant so people are attracted due to occupational purposes.
