Plants in a certain community have been found to use different forms of nitrogen. For example, Plant Species 1 will use nitrate, Plant Species 2 will use ammonium, and Plant Species 3 will use nitrite.
Which of the following is the BEST explanation for this behavior?
Elimination Tool
Select one answer
А
Reducing interspecific competition allows the plant species to survive together.
B
Plant Species 1 outcompetes the other species for nitrate, forcing the other species to use other
forms of nitrogen.
С
Since nitrate, ammonium, and nitrite are all forms of nitrogen, these plant species will compete with
each other until only one species remains.
D
Plant Species 1 converts nitrate into ammonium for Plant Species 2. Plant Species 2 then converts
ammonium into nitrite for Plant Species 3.
