The diagram below shows a food web in a woodland. A food web diagram showing cornstalks with two arrows pointing away from it. One of the arrows points to the letter X and the other arrow points to a grasshopper. There are two arrows pointing away from the grasshopper. One is pointing to a baby sparrow and the other to the letter Y. There is an arrow pointing away from the baby sparrow to a snake and an arrow pointing away from the letter X to the snake.

If a certain organism is a secondary consumer, what best explains its position in the food web? (3 points)

a
X, because organism X feeds on producers

b
Y, because organism Y feeds on producers

c
X, because organism X feeds on a carnivore

d
Y, because organism Y feeds on a herbivore

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
