Answer:
Snapper population is decreasing
Explanation:
The population is decreasing since the human population is increasing dramatically. As the human population increases, the demand for fish and seafood also increases since humans eat seafood and fish. As the demand for fish increases, fishermen fish for these snappers more often and in bigger loads. Snappers cant reproduce faster than these fishermen are hunting for them and so the population decreases
Answer:
The correct answer is d. Oxygen
Explanation:
Phytoplanktons are responsible for the fixation of approximately half of the global carbon therefore seawater has high CO2 concentration which is required by phytoplanktons to make their food.
They are the primary producers of oceans and they are responsible to support the food chain of oceans. Factors that can limit their growth are mainly sunlight and nutrients like phosphorus, nitrogen, etc.
As phytoplanktons are photosynthetic they release oxygen itself as a byproduct therefore oxygen is not a limiting factor to phytoplanktons. So the right answer is d.
