Ecological pyramids are drawn where predators are above prey and they show the population number of each organism shown. Therefore, as the pyramid rises, the population number of the organism decreases, ultimately resulting in a roughly pyramidal shape. Since, organisms higher up the food chain tend to be less numerous than those at the preceding trophic levels, the pyramid is often the classic pyramidal shape. The difference in numbers of organisms at different levels can be so great that logarithmic scales have to be used.
B biosphere that the correct awnser
Answer:
1. Bacteria cannot live above 100 degrees Celsius; archaea can thrive in extreme temperatures. Archaea are actually extremophiles. They can survive in extreme physical and geochemical conditions.
2. Bacterial cell walls have peptidoglycan (mesh-like structure also known as murein); archaeal cell walls do not have peptidoglycan.
The study of microorganisms is called microbiology
