The answer is Cellulose. It does not provide calories/energy. The human digestive tract cannot break it down, so it is indigestible in humans.
Food chains don’t have infinite links, because only about 10% of energy is passed upwards in trophic levels. So a mouse could eat 10 grasshoppers, but a hawk would need to eat 100 mouses to get the same energy
Option B. A man pushes a couch across the room is the answer.
Answer:
D
an increase in the length of the fatty acid tails.
Explanation:
As average annual temperatures decrease, we would expect to find phospholipids within the cell membranes of organisms to have both saturated
and unsaturated fatty acid tails. Saturated fatty acids tails are arranged linearly, in a way that maximizes interactions between the tails and
decreases bilayer fluidity. Unsaturated fatty acids, on the other hand, have more distance between the tails, fewer intermolecular interactions and
more membrane fluidity. Longer tails and decreased cholesterol also decrease fluidity
