How are algae and polyps related

The polyps embedded themselves in the flesh of the algae
The polyps get most of their food from the algae
The pulps receive carbon dioxide from the algae
The pulps receives shelter from the algae

Algae and polyps have a mutualistic relationship where they depend on each other for survival. The correct statement that relates them is: The polyps get most of their food from the algae.

Polyps are small, simple organisms that belong to the phylum Cnidaria, which includes animals such as jellyfish, sea anemones, and coral. Polyps can form colonies and live in symbiosis with photosynthetic algae called zooxanthellae. These algae live inside the tissues of the coral polyps and provide them with food through photosynthesis. The algae use sunlight to produce energy-rich organic compounds such as sugars, which are then used as a food source by the polyps.

In return, the polyps provide the algae with shelter and access to sunlight. The polyps form a calcium carbonate skeleton, which creates a protective habitat for the algae. Additionally, the polyps help regulate the microenvironment around the algae, ensuring that they receive an adequate supply of nutrients and carbon dioxide for photosynthesis.

Overall, the relationship between algae and polyps is beneficial for both parties involved, as the algae provide food for the polyps, and the polyps provide shelter and resources for the algae to thrive.
