An external covering is a covering that is on the outside of an object. This could be anything from skin on humans to hard coverings like those on amoebas, fur on animals like bats, and scales on reptiles.
can you please tell me the answer
Yes, like the hard outside covering on a beetle. (Its the outer covering of insects)
The prefix exo- is not a word in itself. It is added to root words to indicate the meaning "outside" or "outward".Some examples are exobiology (study of theoretical non-terrestrial lifeforms), exothermal (releasing heat to the outside) and exoskeleton (the hard covering of animals who usually have no internal skeleton).
Some seeds have an outer covering which makes it hard for insects and animals to get into. Sunflower seeds have a hard outer shell to protect itself from predators.
some fish and some reptiles
some hard core beastality
Some seeds are hard outside so they pass through the birds' guts and are dropped on the ground...
