So is it five percent @MsSue
To find the percentage of animals on Earth that are vertebrates, we need to determine the ratio of vertebrates to the total number of animals and then convert it to a percentage.
There are roughly 1.3 million known species of animals on Earth. Of these, vertebrates include mammals, birds, reptiles, amphibians, and fish.
According to scientific estimates, vertebrates make up about 5% of the total number of animal species. Therefore, the correct answer is 5%.
