Answer:
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
