Overview of Coral Characteristics
Corals are fascinating marine organisms that play a vital role in marine ecosystems. Let's evaluate the statements provided:
1. Corals are marine invertebrate species.
- This statement is correct. Corals belong to the phylum Cnidaria and are classified as invertebrates, meaning they lack a backbone.
2. Corals secrete calcium carbonate which forms the outer skeleton.
- This statement is also correct. Corals produce calcium carbonate (CaCO3) through a process called calcification, creating a hard exoskeleton that provides structure and protection to the coral polyp.
3. Corals grow in shallow waters to absorb sunlight for photosynthesis to produce their food.
- This statement is partially correct but not entirely accurate in the context of the question. While corals do grow in shallow waters, it is primarily their symbiotic relationship with zooxanthellae (algae) that allows them to utilize sunlight for photosynthesis. However, corals themselves do not produce food independently; they rely on these algae for energy.
Conclusion
Based on the analysis:
- The first two statements are fully correct, while the third one is misleading as it suggests corals produce their food independently. Therefore, the correct answer is option 'A' (1 and 2 only).
This understanding highlights the biological and ecological importance of corals in marine environments.

- Live coral is colonies of small animals embedded in calcium carbonate shells. It is a mistake to think of coral as plants or rocks. Coral heads consist of accumulations of individual animals called polyps, arranged in diverse shapes.
- Reef-building or hermatypic corals live only in the photic zone (above 50 m), the depth to which sufficient sunlight penetrates the water, allowing photosynthesis to occur.
- Coral polyps do not photosynthesise, but have a symbiotic relationship with zooxanthellae; these organisms live within the tissues of polyps and provide organic nutrients that nourish the polyp. Because of this relationship, coral reefs grow much faster in clear water, which admits more sunlight.
