What is the approximate ratio of animals and plants species in our country?

Options

A. `3:1`
B. `2:1`
C. `1:3`
D. `1:2`

Answer

To determine the approximate ratio of animal and plant species in our country, we can follow these steps:

1. **Identify the number of plant species**: According to the information provided, there are approximately 47,000 species of plants in India.

2. **Identify the number of animal species**: The transcript states that there are around 81,000 species of animals recorded in India.

3. **Calculate the ratio**: To find the ratio of animal species to plant species, we can express it as:
\[ \text{Ratio} = \frac{\text{Number of Animal Species}}{\text{Number of Plant Species}} = \frac{81,000}{47,000} \]

4. **Simplify the ratio**: To simplify this ratio, we can divide both numbers by 47,000:
\[ \text{Ratio} = \frac{81,000 \div 47,000}{47,000 \div 47,000} = \frac{81}{47} \]
This can be approximated to a simpler form. Since 81 is roughly double 47, we can express the ratio as approximately 2:1.

5. **Conclusion**: Therefore, the approximate ratio of animal species to plant species in India is 2:1.
