Energy is primarily ________ between entities in biological systems.

Energy is primarily transferred between entities in biological systems due to the fundamental principles that govern energy dynamics in nature. In biological contexts, organisms obtain energy from their environment, for instance through processes like photosynthesis in plants or consumption of food in animals. This energy is not created or destroyed; rather, it transforms from one form to another (e.g., chemical energy to kinetic energy) or moves from one entity to another.

In biological systems, energy transfer occurs between organisms and their environments, like when plants convert sunlight into glucose, which can then be consumed by herbivores and subsequently transferred to carnivores in a food chain. The concept of energy transfer is essential for understanding metabolic processes, cellular respiration, and ecological relationships, highlighting that energy continuously moves and changes form rather than being created anew or simply dispersed, which refers to a less organized form of energy distribution. Thus, recognizing energy transfer is crucial for grasping how living systems function and sustain life.
