What is the primary function of nutrient cycling in aquatic ecosystems?
To maintain the balance of nutrients needed for aquatic life
To control the temperature of the water
To promote artificial feeding of fish populations
To remove pollutants from water bodies
How does nutrient cycling directly affect aquatic biodiversity?
By promoting the growth of phytoplankton, which forms the base of the food web
By increasing water temperature, which encourages species diversity
By decreasing the number of competitors among species in the ecosystem
By ensuring that all aquatic species thrive equally in nutrient-rich environments
What role do decomposers play in nutrient cycling within aquatic ecosystems?
They break down organic matter, releasing nutrients back into the water
They compete with plants for nutrients, reducing biodiversity
They create barriers that prevent nutrients from feeding aquatic life
They increase the oxygen levels in the water through biological processes
