Bacteria and restriction enzymes
,use enzymes to cut (and thereby destroy) foreign DNA (such as viral DNA), which would restrict the growth of the virus; own DNA is protected in some way (often by addition of methyl group CH3) to the sequence recognized by enzyme (thus preventing enzyme from binding there)

Food chains are for example something that another thing eats and it goes down to many different selections and starts off big and vies to small things
