Help fertilize the soil by shedding digestive materials?

Organisms such as earthworms and certain microorganisms play a crucial role in fertilizing the soil by breaking down organic matter, including dead plants and animal waste. As they digest these materials, they excrete nutrient-rich castings that enhance soil fertility. This process not only recycles essential nutrients but also improves soil structure and aeration, promoting healthy plant growth. Ultimately, these digestive materials contribute to a more sustainable ecosystem.
