look at the ocean system below plankton, shrimp, salmon, human what will most likely happen if the plankton population decrease in this ocean systems? A. it will be more difficult for salmon to find food. B more shrimp will move into the area C. humans will have more available food. D the atmosphere will have more oxygen

Answer: Option A

Explanation:

Food chain is connected as one organism depends on other organism for their food.

Here, the food chain is Plankton→shrimp→salmon→ human

If the population of plankton will decrease then the there will be less food for shrimp and their population will decrease, based on them the population of salmon will also decrease.

So, the correct answer is option A

This is a chain reaction. If the plankton population decreases, there will be a lack of food supply for the shrimp. As a result, the shrimp population will also decrease and the salmon will have trouble finding food.

Thus, the answer is A.
