Answer 1

(54) If a meteor impact or volcanic eruption injected a lot of dust into the atmosphere and reduced the sunlight reaching Earth's surface by 70% for one year, deep-sea vent marine community would only be least affected.
(55) Many bacteria are able to recycle biotic substances such as nitrogenous substances back into the soil, air or water because they are decomposers.
(56) species known only from fossils would be inappropriate to use the biological species concept.
