Final answer:
Organisms in wetlands adapt to their environment to survive by having specialized features to conserve water, regulating solute concentrations, and utilizing nutrients from the soil. Plants and animals both have unique adaptations that facilitate their survival in the wet and dynamic wetland ecosystem.
Step-by-step explanation:
Organisms that live in a wetland obtain the things they need to survive through various adaptations and the availability of water, sunlight, and inorganic nutrients in their ecosystem. Plants in wetlands have special features like leaf hairs and a waxy cuticle to minimize water loss, use sunlight to make sugars, and have roots in the saturated hydric soils, which provide a stable supply of water. Freshwater organisms, such as fish and amphibians, have evolved ways to regulate their internal solute concentrations, such as excreting dilute urine, to adapt to their water-rich environment.
Marine organisms, on the other hand, need to retain water and expel solutes due to higher external solute concentrations. Additionally, the movement of water in these ecosystems, such as tides and currents, can affect the availability of nutrients and food resources. Emergent vegetation in wetlands also plays a critical role, offering habitat and food for various organisms, contributing to the nutrient cycle, and helping to maintain the ecosystem's health.
