Second Year Agricultural Science Test focusing on fish and aquatic life.

Let’s go through each question one by one and pick the correct answer based on what we know about fish, water types, and where they live.

Question 1: People eat fish as a source of ______.
Options: staple / protein
→ Fish is known for being rich in protein, which helps build muscles and keep us healthy. “Staple” usually means a main food like rice or bread — not what fish is primarily eaten for.
✔ Correct answer: protein

Question 2: This fish can be eaten.
Options: shark / koi
→ Some sharks are eaten (like in some cultures), but koi are ornamental fish — kept in ponds for beauty, NOT for eating. So between these two, shark is more commonly eaten than koi.
✔ Correct answer: shark

*(Note: In many places, koi are never eaten — they’re pets. Shark meat is consumed in some regions.)*

Question 3: Salt water fish lives in the ______.
Options: pond / sea
→ Ponds have fresh water. The sea has salt water. So salt water fish live in the sea.
✔ Correct answer: sea

So any two of these would work. Let’s pick guppy and angel since they’re classic aquarium fish.
