The diagram is a pyramid of biomass for a meadow ecosystem. The triangular shape of the diagram is useful for explaining which relationship among the trophic levels in this ecosystem? A triangle-shaped diagram shows meadow grasses at its wide base. Above it are a row of rabbits, mice, and grasshoppers. Above them are snakes. At the top of the triangle is a hawk or eagle. A. The amount of living organic matter is equal at all trophic levels in this ecosystem. B. Third-level consumers in this ecosystem have the greatest amount of living organic matter. C. With each step to a higher trophic level in this ecosystem, the amount of living organic matter increases. D. Third-level consumers in this ecosystem provide living organic matter to producers and other consumers. E. The amount of living organic matter decreases at each trophic level in this ecosystem.

The amount of living organic matter decreases at each trophic level in this ecosystem.

Explanation:

A biomass pyramid shows the flow of energy between various levels. Producers and consumers make up the biomass pyramid, which displays all their comparative masses at the same time. To create the biomass pyramid, the approximate masses are stacked up according to a well-established hierarchy.

The primary producers will lie at the bottom of the biomass pyramid. In this case, grasses, trees, flowers, and shrubs make up the needed fuel for the primary consumers that are up on the food chain.

The primary consumers are herbivores: squirrels, deer, insects, and birds that feed on trees and grasses.

In their turn, the primary consumers are food for the secondary consumers predators: frogs, carnivorous birds, and foxes.

Finally, the tertiary consumers predators sit at the top of the biomass pyramid. In this case, a bear closes the  food chain.

The amount of organic matter that can be found in any living organism is called biomass. To convey the biomass present in organisms at various trophic levels, biomass pyramids will indicate the connection between the trophic level and biomass by quantifying the latter.

The quantification uses grams per meter² to represent the volume of organic matter that can be found in an ecosystem at a given time.

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
