Final answer:
The two major aspects of the structure of an ecosystem are the abiotic components and the biotic components.
Step-by-step explanation:
The two major aspects of the structure of an ecosystem are the abiotic components and the biotic components.
Abiotic components include the non-living factors in the ecosystem, such as temperature, sunlight, soil, water, and nutrients. These factors greatly influence the distribution and composition of organisms within the ecosystem.
Biotic components, on the other hand, refer to the living organisms in the ecosystem, including plants, animals, fungi, and microorganisms. These organisms interact with each other and their environment, playing crucial roles in the functioning of the ecosystem.
