Final answer:
Energy is transferred through food chains and webs in ecosystems, with each transfer resulting in a loss of energy. Organisms acquire energy through processes like photosynthesis and consuming other organisms.
Step-by-step explanation:
Energy is transferred from one organism to another through food chains and food webs. Organisms acquire energy through processes like photosynthesis, chemosynthesis, and consuming other organisms. Each transfer of energy results in a loss, which can be visualized in an energy pyramid. The flow of energy through ecosystems is essential for the survival and functioning of all organisms.
