There are three species of birds on an island. Bird A has a heavy bill for eating seeds. Bird B has a pointed bill for eating insects. Bird C has a sharp bill for eating both insects
and seeds. If all insects on the island suddenly disappeared, which bird or birds would
be the LEAST affected?

Please help

A and C would least be affected

Explanation:

because a doesn't live off of insects and see if insects do disappear it still has seed stuff all back on

sound moves fastest in solids because the molecules are tightly packed and it allows sound to vibrate

these objects are classified under the concussion or idiophone group.
