One way scientists group species is when they check their appearance and how closely related they are to other organisms
by having backbone or not
yes, because of their long necks scientists believe that they are the 4th most important animal!
If you mean by main group, vertebrates, because they are invertebrates. But if by main, you mean greatest by number then whether you count them as one celled animals or invertebrates they are much more numerous. They are certainly important to us. Scientists are saying that more than half of the cells in our body are bacteria. If this is so then my little one celled guys are very important to me. What do you mean by main group??
first they observed each organism carefully. then they compared and contrasted their observations with known plants and animals. they tried to place similar organisms in one group. a plant or animal that was very different from others would be put in a new group
why do animals group themselves in one place
Camera traps are one means that scientists use to do this.
Archimedes .
it is important because we do not know if one scientist's results will be the same as another. I hope I've helped=]
Biologists may use an identification key to order or classify a specific group of animals, for example frogs and bears.You immeadiatly see that one is an amphibian and one is a mammal but scientists use these for the minor details.
Scientists use a classification system called taxonomy to categorize plants and animals based on their shared characteristics. This system groups organisms into hierarchical categories like kingdom, phylum, class, order, family, genus, and species. By classifying organisms in this way, scientists can better understand their relationships, evolutionary history, and biological characteristics.
Communication. :)
It is important for scientists to work together from different fields because think of it as a jigsaw one workes on one corner while you work on the other.
the animals group is night animals specially bats
