Entre los seres vivos de un ecosistema, la energ├нa fluye en un solo sentido, desde los organismos aut├│trofos, o productores, es transferida hacia los consumidores mediante las relaciones alimentarias. En cada transferencia, se producen grandes p├йrdidas de energ├нa en forma de calor, el cual es emitido al ambiente. Cuanto de energ├нa se pierde en cada eslab├│n de la cadena tr├│fica

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
