Answer C
Explanation:
Correct. The author uses the two commas to separate three comments, introduced by “But you will tell me,” that his audience could make to counter his earlier argument about nineteenth-century artists’ relationship to their surroundings. By using commas this way, the author is able to quickly identify and distinguish among three related claims within a potential counterargument to his own views. Doing so allows him to begin refuting this counterargument in the next paragraph.

Explanation:
Pyramid of energy is also referred to as food pyramid and it's a model used to depict the flow of energy from one trophic level or feeding level to the next in an ecosystem. It's a diagram that compares the energy used by organisms at each trophic level of the food chain. The pyramid of energy must never be inverted or turned upside down.
The units used in the construction of pyramids of energy is kilocalories (kcal) or energy per area per time (Jm-²year-¹).
A list of the types of organisms in an eco pyramid are;
I. Producers: these are autotrophs or self-feeders such as plants.
II. Primary (top) consumers: these are herbivores that typically feed on plants such as a goat or deer.
III. Secondary consumers: these consists of carnivores that typically feed or eat flesh such as lion, tiger, cheetah, etc.
IV. Tertiary consumers: these are higher predators such as humans that aren't normally fed on by other organisms in the ecosystem.
In Biology, producers are the living organisms that are capable of manufacturing their own food and as such can provide energy or food for the other living organisms (consumers) in a food web. Thus, producers are mainly known as the foundation of a food web (chain) and are at the top.
A producer gets energy from the sun and converts it into food. The cells found in producers are capable of converting the energy received directly from the sun into food through a process generally referred to as photosynthesis, converting carbon dioxide from the air, water from the soil, minerals and energy from the sun into organic nutrients.
