The statement below is followed by four options. Each option is related to the item in the statement, but only one is always true. Select the option that always holds and makes the statement true.
"A herbivore always feeds on ______."
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Plants or plant parts
The answer must hold for every herbivore, without exception. An option that is present in most cases but can be missing in even one case is not always true.
Option (1) Fruits only — a cow feeds mainly on grass and fodder, not on fruits only.
Option (2) Grass only — a giraffe feeds on the leaves of tall trees, not on grass only.
Option (3) Plants or plant parts — a herbivore is an animal that eats only plants or plant products — grass, leaves, fruits or seeds; an animal that eats other animals is not a herbivore, so this is always true.
Option (4) Flesh of other animals — this is never true: animals that eat flesh are carnivores.
