Explanation:

Question 1

Corals are marine invertebrates, which are animals. Plants perform photosynthesis, bacteria are single - celled prokaryotes, and algae are a different group of organisms. So corals are animals.

Coral reefs are formed from the exoskeletons of corals, which are made of calcium carbonate ($CaCO_3$). Brachyura is a taxonomic group of crabs, carbon dioxide is a gas, and mangosteen is a fruit.

Coral reefs require salt water and specific temperature and light conditions. They are found on seamounts, around islands, and in shallow, warm equatorial waters. Rivers have fresh water, so coral reefs are not found in shallow, fresh water in rivers.

Answer:

a. Animals
