Do prokaryotic organisms carry out<br> cellular respiration? If so, how?
Stella [2.4K]

Hi

Do prokaryotic organisms carry out  cellular respiration? If so, how?

The answer is yes as well as no, because some prokaryotes like Archeae and some bacteria donot use cellular respiration because they are anaerobic. The Archaea are also known as Methanogens that reduce Carbon di oxide from environment to Methane that is eventually oxidized to NADH (that is used as an energy source).

However, there are some bacteria that use cellular respiration as a source for the energy production.Cellular respiration is a process which occurs in the cells of higher living organisms as well as in cells of some small organisms like Bacteria. During process of cellular respiration in bacteria, glucose is broken down with the help of oxygen into water and Carbon di oxide. In the process of cellular respiration, bacteria just like humans goes through three stepsi.e Glycolysis, Kreb cycle and Electron transport chain that ultimately lead to the production of ATP (energy).

Hope it helps!

In a lake with three trophic levels (non-native fish, zooplankton, algae), an algal bloom occurs when the small population of zo
aev [14]

Answer:

The small population of zooplankton have an unequal effect on the marine community.

Explanation:

According to this question, there are three trophic levels of organism in a lake as follows: non-native fish, zooplankton, and algae. However, due to the declination in the number of zooplanktons in the lake as they were fed on by the non-native fish, the algal population increased to form a BLOOM.

This bloom of algal species can be attributed to the lack of zooplanktons, which represented the only herbivorous (plant eaters) organism in that community. Hence, their relatively small population have an unequal effect on the marine community. This means that the small population of zooplanktons caused an imbalance in the community and this is why ZOOPLANKTON is the keystone species in this scenario.
