Final answer:
An ecosystem is composed of interacting biotic and abiotic components that work together to move energy and matter. Producers such as plants capture energy through photosynthesis, which supports the ecosystem.
Step-by-step explanation:
An ecosystem is a set of interacting components that form a complex whole, including its community of living things (biotic components) and nonliving environmental factors such as water and sunlight (abiotic components). Ecosystem processes move energy and matter through the biotic and abiotic components of an ecosystem, starting with primary production by producers such as plants. Through photosynthesis, plants capture energy from sunlight and make organic molecules from inorganic compounds.
