1) A simplified nitrogen cycle in the ocean is shown here. The movement of nitrogen can impact algae growth, particularly the phytoplankton populations shown here. Large marine mammals, like whales,
move to the surface of the ocean and release nitrogenous wastes in the form of ammonia. Analyze the nitrogen cycle and select the logical explanation on the impact of the phytoplankton populations
A) Phytoplankton populations will increase as nitrogen availability increases at the surface.
B) Phytoplankton populations will decrease because the ammonia is toxic to the phytoplankton,
C) Phytoplankton populations will decrease as nitrogen influx will cause the phytoplankton to be outcompeted by the bacteria.
D) Phytoplankton populations will not increase nor decrease because ammonia is not a usable form of nitrogen for the phytoplankton
The Practice

Answers

Answer:A) Phytoplankton populations will increase as nitrogen availability increases at the surface.

Phytoplankton populations will increase as nitrogen availability increases at the surface. So, the correct option is (A).

What is Nitrogen cycle?

The nitrogen cycle is defined as the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates in atmospheric, terrestrial and marine ecosystems where nitrogen is transformed through both biological and physical processes.

The steps which are involved in this process:

Nitrogen fixation.Assimilation.Ammonification.Nitrification.Denitrification.Dissimilatory nitrate reduction to ammonium.Anaerobic ammonia oxidation.

It is a repeating cycle of processes during which nitrogen moves through both living and non-living things such as the atmosphere, soil, water, plants, animals and bacteria. In order to move to different parts of the cycle, nitrogen must change form. In this cycle , the phytoplankton increases the nitrogen availability.

Thus, Phytoplankton populations will increase as nitrogen availability increases at the surface. So, the correct option is (A).
