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

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
