Answer:
The size is reduced as 80-95% of the available energy at one trophic level is not transferred to the next
Explanation:
There is loss of energy as it is transferred between trophic levels. The decrease in energy as it moves up the pyramid is due to energy loss as metabolic heat when one organism is consumed by another from the next level as it moves up the trophic levels.
A common resource (or the "commons") is any scarce resource, such as water or pasture, that provides users with tangible benefits but which nobody in particular owns or has exclusive claim to. A major concern with common resources is overuse, especially when there are poor social-management systems in place to protect the core resource.
The subatomic parts of an atom are the protons, neutrons, and electrons. Protons have a positive charge, neutrons have a neutral(no) charge, and electrons have a negative charge.
Hadean is the first eon of precambrian, and took place around 4.6 and 4.0 billion years ago.
