Daphnia is a small water invertebrate that is almost transparent. like all animals, daphnia require chemical energy to live. it uses structures called gills to extract oxygen from the water to it obtain chemical energy. which statement below describes how they obtain chemical energy?

Daphnia obtain chemical energy by absorbing blucose from algae. Then it is used in cellular respiration to produce nicotinamide adenine dinucleotide(NADP) which is chemical energy. Daphnia require chemical energy in the form of NADP. So, it uses gills to extract oxygen from water (H2O) to help it obtain chemical energy.      

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
