Prairie grasses grow from the base of the plant near the ground rather than from the tips of branches. these grasses also have hard materials in their cell walls that make it difficult for animals to crush and digest. cattle have teeth and digestive tracts that enable them to chew and digest prairie grasses. which concept best explains this example?

The symbiotic relationship of ruminants and the cellulose digesting micro organisms

Explanation:

Prairie grass contains cellulose in their cell walls and animals like cattle cannot break them by themselves as they lack the enzymes required. Instead they possess multi chambered stomach containing cellulose digesting microorganisms such as bacteria , to help break down the cellulose contained in the grass .

This relationship is symbiotic as the cattle provides steady supply of food and a dwelling place for the microorganisms, which in turns digest the cellulose rich meal of the cattle.

Their teeth (molars) are also modified for chewing the grass

helicase, i think thats it
