Why is it important you have both soluble and insoluble materials on earth?

Both soluble and insoluble materials are crucial for maintaining ecological balance and supporting life on Earth. Soluble materials, like nutrients and minerals, are essential for plant growth and are easily absorbed by organisms, while insoluble materials, such as rocks and soil, provide structure and habitat. Together, they facilitate processes like water filtration, nutrient cycling, and soil formation, contributing to healthy ecosystems. This diversity supports various life forms and helps sustain the planet's environmental health.
