Which factors primarily drive the environmental changes observed in ecosystems?

The correct answer highlights the significance of both biotic and abiotic interactions as primary drivers of environmental changes in ecosystems. Biotic interactions refer to the relationships and dynamics between living organisms within an ecosystem, such as predation, competition, symbiosis, and mutualism. These interactions can significantly influence population dynamics, species diversity, and overall ecosystem health.

Abiotic factors, on the other hand, encompass the non-living components of an ecosystem, including climate, soil, water, sunlight, and temperature. Changes in abiotic conditions can lead to significant shifts in ecosystems, such as altering the habitat that affects the species living there. For example, a change in water availability can affect plant growth, which in turn impacts herbivores and the predators that feed on them.

In combination, the interplay between biotic and abiotic factors shapes the structure and function of ecosystems. This interaction can lead to gradual changes over time, such as succession, or more abrupt changes due to events like natural disasters or human activities.

While human intervention and climate change, species prevalence and density, and geological formations do play roles in environmental changes, they are often manifestations or specific examples of the broader interactions between biotic and abiotic factors. Thus, understanding the fundamental principles of
