which of the following is a significant ecosystem service provided by seagrass meadows?
providing carbon sinks and highly productive nurseries
providing shelter for coastal zones from large, destructive storms
by adding metals and toxins to the water

Explanation:

First Question (Producer in mangrove ecosystem):

Producers in an ecosystem are organisms that can perform photosynthesis to make their own food, typically plants or algae. Red mangroves are plants (trees) that can photosynthesize, so they are producers. Birds of prey, crabs, and reptiles are consumers (they eat other organisms) and not producers.

Seagrass meadows are known for being carbon sinks (storing carbon) and serving as nurseries for many marine species (highly productive nurseries). Providing shelter from storms is more associated with mangroves or coral reefs. Adding metals and toxins to water is not a positive ecosystem service and is incorrect. So the correct option is the one about carbon sinks and nurseries.

Answer:

A. Red mangroves
