The ways in which understanding one level of ecological organization helps in understanding the process of a higher level of ecological organization.
The ecosystem includes a small level and a large level of organization. The smaller level of the ecological organization includes species and population, while the larger level includes community, ecosystem, and biosphere. All the levels of the ecological organization are interlinked to each other, and any change in one level might alter the structure of other levels.
Ecology is a branch of biology that studies the interaction between environment and organisms. In ecology, researchers specifically work on four levels that include organism, population, community, and ecosystem. All these levels are dynamically interacting with each other and with abiotic factors.
Ecosystem processes such as nutrient cycling and pedogenesis (formation of soil) are affected by the population. If the human population increases drastically, there are chances that it degrades the formation of soil or leads to deforestation. Similarly, a diseased oak tree might restrict the growth of insects that feed on the oak tree. Thus, understanding one level of ecological organization helps in further understanding of other levels of the organization.
