Mangroves are unique and highly productive ecosystems that are found in tropical and subtropical intertidal regions. They are characterized by salt-tolerant plant communities and are vital for coastal protection, providing habitats for numerous species, and contributing to carbon sequestration.

Statement 1: Mangroves are salt-tolerant plant communities found in both tropical and subtropical intertidal regions.
This statement is correct. Mangroves are found in coastal areas where the land meets the sea. They are capable of thriving in saline conditions and are adapted to withstand tidal fluctuations.

Statement 2: In India, Gujarat has the highest mangrove cover.
This statement is incorrect. According to the State of Forest Report 2019 published by the Forest Survey of India, the state of West Bengal has the highest mangrove cover in India, followed by Gujarat and Andaman and Nicobar Islands.

Statement 3: In India, there has been a decrease in the mangrove cover from 1990 to 2021.
This statement is not mentioned in the question and cannot be determined from the given information. Therefore, it is incorrect to consider it as a correct statement.

In conclusion, only statement 1 is correct, and statement 2 is incorrect.

A species that exertsan influence out of proportion to its abundance in an ecosystem is called a keystone species. The keystone species may influence both the species richness of communities and the flow of energy and materials through ecosystems. The sea star Pisaster the flow of energy and materials through ecosystems. The sea star Pisaster ochraceus, which lives in rocky intertidal ecosystems on the Pacific coast of North America, is also an example of a keystone species. Its preferred prey is the mussel Mytilus californianus . In the absence of sea- stars, these mussels crowd out other competitors in a broad belt of the intertidal zone. By consuming mussels, sea star creates bare spaces that are taken over by a variety of other species. A study at the University of washington demonstrated the influence of Pisaster on species richness by removing sea stars from selected parts of the intertidal zone repeatedly over a period of five years. Two major changes occured in the areas from which sea stars were removed. First, the lower edge of the 46. mussel bed extended farther down into the intertidal zone, showing that sea stars are able to eliminate mussels completely where they are covered with water most of the time. Second, and more dramatically, 28 species of animals and algae disappeared from the sea star removal zone. Eventually only Mytilus, the dominant competitor, occupied the entire substratum. Through its effect on competitive relationships, predation by Pisaster largely determines which species live in these rocky intertidal ecosystems.Q. With reference to the passage, consider the following statements : 1. Mussels-are generally the dominant species in intertidal ecosystems. 2. The survival of sea stars is generally determined by the abundance of mussels. Which of the statements given above is /are correct?
