the amount of available energy changes between the trophic levels found in a food chain or energy pyramid. photos (left to right) by mehmet karatay, jens buurgaard nielsen, furryscaly, and walter siegmund in the food chain shown, which of the following changes between trophic levels would have the highest energy conversion efficiency? a) leaf to mouseb) mouse to snakec)snake to hawkd)all changes would have the same efficiency

In a food pyramid, the organisms at the lower level of the food chain directly get their energy from the sun and are referred to as primary producers. This level contains mainly of plants. The organisms that are on the next levels are the primary, secondary and tertiary consumers respectively. The energy conversion level is the highest at the lowest trophical level and as the levels move up the level of energy conversion gets lower.

Here out of the choices we are given we need to find which of these changes are at the lowest trophical levels. The option leaf to mouse is at the lowest level since leaf or plant is a primary producer and hence the energy conversion level is the highest compared to the other options

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.
