Let's Learn our Islam by Harun Yahya - page 35

Bees carry the
pollen of the
flowers they
visit to other
flowers. This is
the process that
ensures the
reproduction of
flowers.
Similarly,
cleaning fish
clean larger fish.
There is a balance
in the creation of
living things in
nature. Owing to
this flawless
balance, they can
survive as species
for millions of
years.
