Final answer:
The claim that living organisms do not play a part in the water cycle is false, as plants and animals actively contribute through transpiration and other metabolic processes.
Step-by-step explanation:
The statement "Living organisms do not play a role in the water cycle." is false. Living organisms, especially plants, are integral to the water cycle. For example, during the process of transpiration, water vapor is released from plants into the atmosphere. Moreover, organisms such as animals contribute to the water cycle through processes like respiration, perspiration, and excretion, further connecting the biotic and abiotic components of the ecosystem.
