How would plant populations be affected if the populations of decompose-rs such as earthworms decreased dramatically?

If earthworm populations decreased dramatically, plant populations would likely suffer due to reduced soil fertility and structure. Earthworms play a critical role in decomposing organic matter, enhancing nutrient availability and promoting healthy soil aeration and drainage. With fewer decomposers, nutrient cycling would be disrupted, leading to poorer plant growth and potentially lower biodiversity. Ultimately, this could result in diminished plant health and productivity, affecting entire ecosystems.
