The correct answer is D. Mangrove ecosystems along the Karnataka coast play a crucial role in fish breeding, nursery grounds, and storm protection.

Mangroves are a type of tree that grows in tropical and subtropical coastal areas. They are adapted to live in salty water and can withstand strong winds and waves. Mangroves provide a number of important ecosystem services, including:

• Fish breeding: Mangroves provide a safe place for fish to breed and lay their eggs. The roots of mangroves create a sheltered environment where fish can spawn and their young can grow.
• Nursery grounds: Mangroves also provide a nursery ground for young fish. The roots of mangroves provide a place for young fish to hide from predators and to find food.
• Storm protection: Mangroves help to protect coastal areas from storms and erosion. The roots of mangroves help to stabilize the shoreline and the leaves of mangroves help to break the force of waves.

Mangroves are an important part of the coastal ecosystem and play a vital role in protecting coastal communities from the effects of climate change.
