The range of the giant panda in world is limited part by availability a kind grass necessary to diet name woody grass?

The giant panda's diet primarily consists of bamboo, and the availability of different bamboo species significantly influences its range and distribution. While the giant panda can consume other plants, bamboo makes up over 99% of its diet.

The specific type of bamboo that the giant panda relies on is called "woody bamboo" or "arrow bamboo." There are several species of woody bamboo that the panda feeds on, including Fargesia panda, Fargesia robusta, Pleioblastus amarus, and Pleioblastus maculatus. These bamboo species are native to the temperate forests and mountainous regions of China, where the giant panda is found.

The giant panda's diet is highly specialized, and it has evolved unique adaptations to consume and digest bamboo efficiently. Its teeth and jaws are designed for crushing and grinding the tough bamboo culms and leaves. Additionally, the panda's digestive system is specialized for breaking down the cellulose and extracting nutrients from the bamboo.

The availability and accessibility of these specific bamboo species play a crucial role in determining the giant panda's habitat and range. The panda's population density and distribution are closely tied to areas with abundant woody bamboo forests. As a result, the conservation and protection of bamboo habitats are essential for maintaining viable populations of giant pandas in the wild.
