Two c atoms form a double bond. each c is bound to two h atoms. which statement is true?
a_the bonds orient like tripods or pyramids.
b_all the atoms lie in a line.
c_the bonds orient in a tetrahedral fashion.
d_all the atoms lie in a plane.
e_the groups rotate around the c=c bond.

i believe the answer is a or 1

a

explanation:

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
