Grass, the world's most important crop
This plant also has important ecological functions: it protects against soil erosion, it absorbs water, it purifies the air we breathe and so on. Every variety of grass has its own special properties.
Grass Conserves Water and Cleans Air
Grass helps trap water by storing it in their roots and blades. It also cleans air through the process of photosynthesis and keeps your yard from eroding away due to rain and wind.
What roles do grass play? Grasses provide forage for herbivores that have developed in conjunction with them. The grazing animals, in their turn, contribute nutrients in the form of dung and urine and increase the rate of nutrient turnover in the ecosystem. Grasses dominate steppe, prairie and savanna plant formations.
