Coastal and marine ecosystems are known for their high productivity, supporting a wide range of organisms.

Migration is the movement of marine organisms between different habitats, often over long distances.

Barnacles are sessile organisms that have adapted to the intertidal zone by attaching themselves to rocks or other hard surfaces, enabling them to withstand the changing tides and wave action.

Nutrient cycling is the process by which nutrients are recycled within a marine ecosystem, involving the transfer of nutrients between organisms and the environment.

Coral reefs are not coastal wetlands, but rather underwater ecosystems formed by the accumulation of calcium carbonate produced by corals.

Reproduction is the process by which marine organisms produce offspring, ensuring the continuation of their species.

Sea turtles are not marine mammals, but rather reptiles that have adapted to a marine environment.

Dispersal is the process by which marine organisms move from one habitat to another, often over long distances.

Tundra is not a coastal and marine habitat, but rather a terrestrial ecosystem found in cold regions.

Ecology is the study of the interactions between marine organisms and their environment, including their behavior, distribution, and abundance.

Deforestation is not a type of coastal and marine pollution, but rather an environmental issue related to the clearing of forests.

Adaptation is the process by which marine organisms adapt to their environment, developing traits that enhance their survival and reproduction.

Invasive species control is not a type of coastal and marine conservation measure, but rather a measure to manage invasive species in terrestrial ecosystems.

Competition is the process by which marine organisms compete for resources, such as food, space, and mates.

Deserts are not coastal and marine ecosystems, but rather terrestrial ecosystems characterized by extreme dryness.
