Ducks have a gland near their tail called a uropygial gland. This gland produces preen oil that serves a number of functions, including waterproofing their feathers. Preen oil consists of lipids such as diester waxes. A duck is omnivorous and its diet consists of small fish, grass, and algae. Which one shows the correct sequence?
Grass absorbs light energy - Grass makes sugar - duck eats grass - duck turns sugar into lipid - duck makes preen oil
Grass makes sugar - duck turns sugar into lipid - duck makes preen oil
Grass absorbs light energy - Grass makes sugar - Duck turns sugar into lipid - Duck makes preen oil
Grass absorbs light energy - grass makes sugar - duck gets preen oil from grass

Most bees consume nectar from flowers, but queen bees eat a substance called royal jelly, which is secreted by other bees in the hive. Royal jelly contains numerous proteins as well as a substance known as queen bee acid. Which answer shows the correct sequence of how royal jelly is made?
Plants absorb CO2 - Plants produce sugar - Bees consume sugar - Sugar molecule are rearranged to make queen acid - bees excrete royal jelly
Plants produce sugars - Bees consume sugar - bees make sugar - bees excrete royal jelly
Plants absorb CO2 - Plants produce sugar - Bees consume queen acid from plants - bees excrete royal jelly
Plants absorb CO2 - Plants make sugar - Plants make queen acid - Bee consume queen acid from plants - Bees excrete royal jelly
