Question

Mixing of nutrients from saltwater and freshwater, combined with plentiful sunlight and relatively shallow water, makes estuaries very _____________ ecosystems.

Answer 1

Estuaries are diverse ecosystems where saltwater and freshwater mix. These environments provide ideal conditions for the growth of various organisms, and the mixing of nutrients makes them rich in biological activity. However, the variation in salinity poses physiological challenges for the plants and animals that live in estuaries.

Step-by-step explanation:

Estuaries are very diverse ecosystems due to the mixing of nutrients from saltwater and freshwater. The combination of plentiful sunlight and relatively shallow water in estuaries creates ideal conditions for the growth of various organisms. For example, estuaries provide protected areas for the young offspring of crustaceans, mollusks, and fish to begin their lives. The variation in salinity resulting from the mixing of fresh water and salt water in estuaries presents a physiological challenge for the plants and animals that inhabit these environments, leading to the development of specialized adaptations.
