An energy pyramid is a graphical model of energy flow in a community. the different levels represent different groups of organisms that compose a food chain. an energy pyramid’s shape shows how the amount of useful energy that enters each level. chemical energy, in the form of food, decreases because some is used by the organisms in each level. the source of the chemical energy is the producers, that rearrange carbon dioxide and water in the presence of light to make through the process of

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
