Which situation is an example of competition that could be found in the ocean? two shark populations utilize the same fish population as their main food source

algae blooms decrease as the number of fish increase

lack of sunlight due to changes in the seasons restricts the growth of certain plants

plentiful oxygen leads to an increase in the number of reefs

A. two shark populations utilize the same fish population as their main food source

I'm guessing this is from Marine Biology. I know this is an example of competition because two different groups of sharks are eating food from the same source. If one group gets to it first every time, they could leave the other group with no food. So it is a competition.

littering streams           is the answer

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
