A coral reef
B
A desert biome
C
An estuary
D
A tundra ecosystem
Verified step by step guidance1
Understand the definition of an estuary: An estuary is a coastal area where freshwater from rivers and streams mixes with saltwater from the ocean, creating a unique and highly productive ecosystem.
Identify the geographical and ecological characteristics of the Mississippi Delta: It is located at the mouth of the Mississippi River, where the river meets the Gulf of Mexico, making it a prime example of an estuary.
Compare the Mississippi Delta to the other options provided: A coral reef is a marine ecosystem dominated by coral structures, a desert biome is characterized by arid conditions and low precipitation, and a tundra ecosystem is a cold, treeless region found in polar areas. None of these match the characteristics of the Mississippi Delta.
Recognize the ecological importance of estuaries: They serve as nurseries for many marine species, provide habitat for diverse organisms, and act as natural filters for pollutants.
Conclude that the Mississippi Delta fits the definition of an estuary based on its location, ecological role, and the mixing of freshwater and saltwater.
