Ratio of Animals and Plant Species in India
India is known for its rich species diversity, with varying physical conditions and species grouping across the country. The country is divided into 10 biogeographical regions, each with its distinct characteristics and ecological features. The tropical regions, in particular, are considered to be a rich centre of biodiversity due to the favorable conditions they provide throughout the year, such as warm temperatures and high humidity.
Importance of Rich Species Diversity
Rich species diversity is crucial for the stability and productivity of ecosystems. It plays a significant role in maintaining ecological balance, as different species have unique roles and functions within their respective habitats. Here are some reasons why rich diversity is important:
1. Stability: Biodiversity enhances the resilience of ecosystems, making them more resistant to disturbances such as climate change, diseases, and invasive species. A diverse ecosystem can better adapt to changes and recover from disruptions.
2. Productivity: Different species contribute to the overall productivity of ecosystems. For example, plants are primary producers that convert sunlight into energy through photosynthesis. Animals, on the other hand, play roles as pollinators, seed dispersers, and predators, contributing to the overall functioning of the ecosystem.
3. Ecosystem Services: Biodiversity provides various ecosystem services that are essential for human well-being. These services include clean air and water, nutrient cycling, soil fertility, and natural pest control. The loss of biodiversity can lead to a decline in these services, affecting human livelihoods.
Approximate Ratio of Animals and Plant Species in India
The approximate ratio of animals to plant species in India is 2:1, as indicated by option B. This means that for every two animal species, there is approximately one plant species in the country. It is important to note that this ratio may vary across different regions and ecosystems within India.
The higher ratio of animal species to plant species can be attributed to the diverse range of habitats and ecosystems present in the country. India's topography encompasses various landscapes, including forests, grasslands, wetlands, deserts, and coastal areas, each supporting a unique assemblage of animal species.
Moreover, the diverse climatic conditions and vegetation types in different regions of India provide suitable habitats for a wide variety of animal species. These animals have adapted to the specific ecological niches available in their respective habitats, resulting in a greater diversity of animal species compared to plant species.
In conclusion, India's rich species diversity is a result of its varying physical conditions and species grouping. The approximate ratio of animals to plant species in the country is 2:1, highlighting the importance of both animal and plant life in maintaining the stability and productivity of ecosystems.
