Question

owl and mouse
zebra and oxpecker
cat and tapeworm
cattle egret and cow
lion and hyena
both
zebra
mutualism
commensalism
predation
cat
neither
tapeworm
hyena
lion

Explanation:

Step1: Determine the relationship type for owl and mouse

Owls hunt and eat mice. This is a classic example of predation.

Step2: Determine the beneficiary in zebra - oxpecker mutualism

In mutualism, both species benefit. Oxpeckers eat ticks and other parasites from zebras, and zebras get pest control. So both benefit.

Step3: Determine the beneficiary in cat - tapeworm parasitism

In parasitism, one organism (the parasite) benefits at the expense of the other (the host). Tapeworms live in the cat's intestines and absorb nutrients, harming the cat. So the tapeworm benefits.

Step4: Determine the relationship type for cattle egret and cow

Cattle egrets follow cows. As cows graze, they stir up insects, which egrets eat. The cow is not significantly affected. This is commensalism.

Step5: Determine the non - beneficiary in lion - hyena competition

In competition, both species are harmed as they vie for the same resources (like food). But since the question asks for the one to fill in (assuming the structure is similar to others), and in the context of the table, we just note the relationship type was given as competition.

Answer:

owl and mouse: predation; zebra and oxpecker: both; cat and tapeworm: tapeworm; cattle egret and cow: commensalism; lion and hyena: both (since in competition, both are affected negatively in terms of resource access, similar to the 'both' in mutualism but in a negative - interaction sense for the context of this table's structure)
