These are the levels of Linnaeus's hierarchical system of classification:
kingdom, phylum, class, order, family, genus, and species.
To prevent the backflow of blood during systole and diastole, Artries from the heart dont need valves since their blood pressure is already high enough to not allow backflow of blood, but since veins' blood pressure is lower, they need valves just so the blood doesn't seep back in into the heart again!
Wet tropical air has a relative humidity of 100 percent
Answer:
If we remove a levels of organization then the study of biology i.e life would become very difficult. We won't be able to differentiate between the tissues, organs and systems of an organism and hence, studying the characteristics of an organism will become extremely difficult. We won't able to look at the similarities among organisms and hence will not be able to relate species to anther.
Removing a level such as community or ecosystem will make it difficult to understand the food chains and food web as well.
<span>Biodiversity is the number of species in a particular ecosystem.
It's generally considered more healthy for an environment to have large numbers of species. Many organisms come to depend on others so when you lose one species, it could cause others to be lost.
Example: Several trees in New Zealand required a giant extinct bird the moas to spread their seeds. They lost the trees because they lost the moas.
