Final answer:
Abiotic factors such as light, temperature, water movement, and salt content play a significant role in influencing the interfaces between terrestrial and aquatic ecosystems.
Step-by-step explanation:
The interfaces between terrestrial and aquatic ecosystems are often influenced by various abiotic factors. Some of these factors include light, temperature, water movement, and salt content. For example, light plays a crucial role in sustaining certain organisms in bodies of water, especially in deep water where sunlight penetration is limited. Other factors like temperature, water movement, and salinity also affect the structure and function of aquatic ecosystems.
