Answer:

1. mutualism 2.parasitism 3. commensalism 4.commensalism 5. parasitism

Explanation:

It states in #1 that both of them benefit from each other, one gets help and the other one gets food.

Ticks are parasites

sharsk do not benefit from the remora but the latter do by eating the shark's leftover

orchids are epiphytes they grow on other plant but the other won't benefit from it

cuckoo will lay her egg on the same nest owned by the warbler. If the (cuckoo's) egg hatched the cuckoo kicked the warbler chick out. so the warbler will end up feeding the cuckoo chicks and not her own child.
