6. Would there be a net flow of water in one direction in the following situations? Explain your answers.
amid [387]

Answer: There won't be a net flow of water in one direction in the situation.

Explanation: The concentration of NaCl inside the cell and its concentration outside the cell is the same. This means that there is equilibrium (a balance) between the inside environment of the cell and the outside environment of the cell. And because there is equilibrium between the two sides there will not be a net flow of water in one direction. The flow of water must be in opposite directions (inside and outside) so as to maintain a balance between the two environments.

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.
