The species butterfly has 20,000 of the 1 million species in the insect group. At any one time there must be thousands of living Cabbage White butterflies flying around so you have 20,000 different types of butterfly flying around and maybe there are 50,000 of each type living at any one time. Help. I must admit the calculations are frightening so i cheated and looked at the work of other scientists who say that there are 8 million species and each species has millions of living specimens.
The homo species (us) has 9 billion living specimens, I suspect the ant population is considerably bigger than that so in answer to your question …. and then think of the number of plants ….and then the number of bacteria …..there is no believable answer. However somebody has tried and they had difficulty putting all the numbers on their sheet of paper. Sorry Kaia.
