White-breasted nuthatches and Downy woodpeckers both eat insects that hide in the furrows of bark in hardwood trees. The Downy woodpecker searches for insects by hunting from the bottom of the tree trunk to the top, while the White-breasted nuthatch searches from the top of the trunk down. These hunting behaviours best illustrate which of the following ecological concepts?

Cellulose microfibrils have an ordered structure and are synthesized at the plasma membrane, given characteristics of microfibrils;

a) Each microfibril is composed of an estimated 18 parallel chains of (1,4)-linked β-D-glucose chains tightly bonded to each other to form a crystalline microfibril

b) Microfibrils have hydrophilic surfaces, populated by polar –OH groups extending from the plane of the sugar rings

c) Microfibrils have hydrophobic surfaces, populated by nonpolar C–H groups populating the sides of stacked glucose chains

 d) microfibril important for enzymatic attack by microbial cellulases, which dock onto the hydrophobic surface and remove one glucan chain at a time

Which of the following from given characteristics of microfibrils is incorrect?
