Explanation:
In all living system we can always find basic elements carbon, oxygen, nitrogen and hydrogen, carbon is the basic building unit contained in living matter. The percentage of carbon in the mass of living matter is 19.0% oxygen and hydrogen are present in almost all organic compound which creates living organisms.
I believe it's the temperature in the core
Primary producers are usually the start of a food web. They make their own energy by converting carbon dioxide sunlight and water into food. Then a secondary producer would be the second part of the food web. They usually are herbivores so they only eat plants, which would be the primary producer. Next, is decomposers, decomposers are organisms break down what’s left of dead or decaying organisms like animals and plants. Hope this helped have a great day :-)
The answer is A. Morphology/anatomy is considered more
relevant than behavior or general appearance in the classification of organisms. It
is due to these anatomical features that animals such as bats are classified differently
from birds (with bats classified as mammals even though they fly like birds) due to differences in anatomical features
like milk-producing glands and brain structure.
