What is the primary role of nitrate (NO3-) ions in the nitrogen cycle?
They are directly absorbed by plants for growth.
They are released into the atmosphere during denitrification.
They serve as a reservoir of nitrogen in the soil.
They are produced during ammonification.
How do fluctuations in water availability impact aquatic biomes?
They do not affect aquatic biomes.
They can lead to shifts in the composition of aquatic plant species.
Water availability only affects terrestrial biomes.
