Which of the following statements regarding the estimates of number of...
The correct answer is option B: "Plants constitute more than 70% of all the species recorded, whereas animals constitute less than 22% of the total number of species."
Explanation:
- Total number of species: The estimate of the total number of species present on Earth is not a fixed number and is subject to ongoing research and discoveries. Different estimates have been proposed by various scientists, and it is challenging to determine the exact number.
- Estimate by Robert May: Robert May, an ecologist, estimated that there are about 7 million species on Earth. However, this estimate is not universally accepted, and other scientists have proposed different numbers.
- Insects as a percentage of animal species: Insects are indeed one of the most diverse groups of animals on Earth. They make up a significant proportion of the animal kingdom, with estimates suggesting that they constitute more than 70% of all animal species.
- Plants as a percentage of all species: It is incorrect to state that plants constitute more than 70% of all the species recorded. In reality, plants represent a smaller proportion of the total number of species compared to animals. While plants are incredibly diverse and play a crucial role in ecosystems, they are outnumbered by the vast array of animal species.
Therefore, option B is not correct, as it inaccurately states that plants constitute more than 70% of all the species recorded, whereas animals constitute less than 22% of the total number of species.
