If saprobic fungal populations were to decline, terrestrial ecosystems would A) release excessive amounts of CO₂. B) continue to break down the same amount of carbon compounds. C) reduce decomposition. D) undergo a mass extinction. E) increase decomposition.

Question

Saprobic fungi play a critical role in decomposition and nutrient cycling in soil. If their populations were to decline, it would result in a reduction of decomposition, as there would be fewer organisms breaking down organic matter. This would likely result in an accumulation of organic material in the soil, slowing nutrient cycling and potentially reducing plant growth. Therefore, option C is the correct choice. The other options are not directly related to the impact of declining saprobic fungal populations on terrestrial ecosystems.
