grass growing is a physical change.
Grasses are plants that grow from their bases, that is why mowing your lawn does not hurt the plant. When a fire sweeps across a grassland, it burns off all the grass but leaves the root system and growing crown unharmed (because they are below the fire in the soil). Within a few days new grass leaves sprout form the root crown and the grass recovers. Other species of plant grow from their tips (the growing shoot) and a fire damages this growing tip (which is above ground).
Zebras mainly eat grass and other ground growing plants. They get it by walking around and grazing.

A creeping stem of a grass plant that grows above ground is called a stolon. Stolons help the plant spread horizontally by producing new roots and shoots at nodes along the stem. They enable the grass plant to form new individual plants connected to the parent plant.
Adventitious is the type of roots that Johnson grass has.Specifically, Johnson grass (Sorghum halepense) has stems above-ground and below. The subterranean stem is designated a rhizome. It produces both roots for anchoring in soil and gathering soil nutrients as well as shoots for increasing photosynthetic and seed-making activities above-ground.
