Final answer:

The statement is true. All life forms on Earth depend on interactions with other Earth systems, such as the atmosphere and hydrosphere, which provide necessary abiotic components like water and air. These systems are crucial for the survival of all terrestrial life and are impacted by biological activities, resulting in observable planet-scale changes.

Step-by-step explanation:

The statement that "All of Earth's life forms require interaction with at least one of the other Earth systems (excluding the biosphere) for their survival" is True. This is because life on Earth depends on intricate interactions with various abiotic factors such as water, sunlight, atmosphere, and soil, which are components of other Earth systems like the hydrosphere, atmosphere, and geosphere. These interactions involve the exchange of matter and energy, critical for the sustenance of all biological systems, from the cellular level right up to whole ecosystems.

The various Earth systems excluding the biosphere, such as the atmosphere, hydrosphere, and lithosphere, provide necessary abiotic components that support life. For example, the atmosphere is crucial for providing oxygen for respiration and carbon dioxide for photosynthesis, while the hydrosphere supplies water, essential for all cellular processes. Moreover, the lithosphere offers minerals and a substrate for plants and many microorganisms.

Furthermore, these Earth systems impact the biosphere by influencing climate patterns, seasons, and weather, which in turn, affects how populations, communities, and ecosystems interact and evolve. For instance, ocean currents and air movement patterns distribute heat around the planet, which influences habitats and the distribution of species.

It's noteworthy that Earth is the only known planet with a biosphere capable of causing planet-scale changes observable through the composition of our atmosphere and the light reflected from our planet. This demonstrates the significant role that the non-biological components of the Earth system play in supporting and being altered by biological activities.
