An animal which is active during the day is known as a

Step 1: Analyze the question The question asks for the term used for an animal that is active during the day.

Step 2: Explain the concept Animals are classified by when they are active:

• Diurnal: active during the day (from Latin diurnus, meaning "daily"). Examples are humans, most birds, and butterflies.
• Nocturnal: active at night. Examples are bats, owls, and cockroaches.
• Crepuscular: active at dawn and dusk.

Step 3: Check each option

• A. Nocturnal animal: active at night, so this is the opposite of what the question asks.
• B. Diurnal animal: active during the day, so this matches.
• C. Terrestrial animal: lives on land. This describes habitat, not activity time.
• D. Homortacmic: this is not a recognised term. It is probably a garbled "homeothermic" (warm-blooded), which concerns body temperature regulation, not daytime activity.

Step 4: Answer The correct answer is B. diurnal animal.

Exam tip: Link Diurnal with Day, since both start with "D". Nocturnal goes with Night, since both start with "N". Questions like this are common in JAMB, so learn these pairs.
