Can an ecosystem survive without plants?
Without plants, life could not exist on Earth as plants impact all four of the critical ecosystem processes that sustain life. … Soil without plant and microbial life is just geology – dirt and rocks! Soil is the intimate union between biology and geology.

How do species support life on Earth?
After all, biodiversity itself appears to control the elemental cycles—carbon, nitrogen, water—that allow the planet to support life. Only by acting in conjunction with one another, for example, can a set of grassland plant species maintain healthy levels of nitrogen in both soil and leaf.
