The cell wall is what gives plant cells their shape. The cell wall, not to be confused with the cell membrane, is a rigid structure made up of long cellulose fibers, branching hemicellulose fibers, and pectin. The fluid pressure inside the cell also contributes somewhat to their shape.
Carbonized remains are thin, approximately two-dimensional films of carbon preserved on a flat surface of rock. They are most often black in color, reflecting the fact that they composed mostly of carbon (as is coal, which is also black in color). Most fossils that exhibit “soft part” preservation are carbonizations.
I would say the answer is the Carbon remains of the original organism.
Answer:
Because primary producers get 100% energy consumption straight from the sun.
Explanation:
We use the energy pyramid to help us out:
.01% - A pex Predators
0.1% - Tertiary Consumers
1% - Secondary Consumers
10% - Primary Consumers
100% - Primary Producers
Because Primary Producers get 100% of the energy of the sun, they can support so many primary consumers, who only get 10% of the energy when they consume primary producers.
The answer is letter B.

Viruses have the ability to reproduce on their own and
sometimes within hosts. It is an infectious agent that can affect all types of
life forms (e.g. animals, plants, microorganisms). They are found in almost
every ecosystem on Earth and they are the most abundant type of biological
identity. Asvirology is the study of
viruses which is a sub-specialty of microbiology. The spread in many ways and
can be transmitted from one organism to another or sometimes to multiple
organisms at the same time. Its origins in the evolutionary history of life is
still unclear but they are considered to be life forms because of their
capacity to carry genetic material, reproduce, and evolve through natural
selection. </span>
