first is photosynthesis. It is
when the sun's rays pass
through the plant
The nectar is produced by
different glands at the base
of the stamens and petals,
called nectaries, often
deposited in bags or rams
base of the corolla.
His long tongue allows
them to suck nectar from
flowers through the
wound structure on the
outside of the tongue
Then Food initially passes to
an elastic sac in the neck called
a crop, which serves the same
storage and supply functions
as a stomach. Small amounts
of food empty from the crop
and pass to the Intestine,
where sugar is assimilated into
the blood.
Hummingbirds are very fast animals, can
flap their wings up to 70 times per second
remaining in the same place while
extracting nectar from the flower.
energy passes from the
nectar to cellular respiration
in the hummingbird’s cells to
generate energy for
movement
