Answer: Energy is passed up a food chain or web from lower to higher trophic levels. This loss of energy explains why there are rarely more than four trophic levels in a food chain or web. Sometimes there may be a fifth trophic level, but usually there's not enough energy left to support any additional levels.
Explanation: :) Hope it helps
These lines (there is four of them) are residuals of the fusion of the five sacrum vertebrae that are fused. These "vertebrae" or segments present a characteristics, being the first of them very similar to a lumbar vertebra, large, and the other vertebrae are<span> progressively smaller and flattened. They also present a curved shape being anteriorly concave.</span>
The answer to this question would be because phospholipid is polar has <span>a </span>charge.
Since phospholipid is polar, it can attract molecule with a charge. That will cause the molecule cant move easily pass the membrane. The hydrophobic molecule doesn't have charge, so the molecule can pass through the phospholipid membrane if it small enough.
