With its deep root system, bermuda grass has adapted to the savanna by dying off above ground during periods of drought, while maintaining growth beneath the soil.

Afterward, they feed it to the animals. Red oat grass is susceptible to heavy grazing and it may suffer a greater risk from overgrazing when other species have declined (Tothill, 1992). A fire followed by a rain favours red oat grass since it increases its seed germination in conditions where others seeds die (FAO, 2011; Ghl, 1982). The most common animals that eat red oat grass are zebras, giraffes, and antelopes. Some plants, such as trees, must develop other strategies to cope with the prolonged droughts.

Well, plants in the savanna have developed defenses for this. Most savanna grass is coarse and grows in patches with interspersed areas of bare ground. Palms are monocotyledons meaning that the veins in their leaves unbranched and parallel, and are thus relatives of lilies, bananas, grasses, and orchids. However, if producer is defined as an organism that provides food for other organisms, then red oat grass would not be considered a producer. it can survive on land depleted by farming; it tolerates extreme changes in temperature; contains 40 per cent more protein than traditional grains used for making, because of the way it grows, forming a very dense tussock with its leaves bending outwards, it protects the soil and creates its own little, This page was last edited on 4 April 2023, at 06:30.
