Explanation:
2. Species interactions form the basis for many ecosystem properties and processes such as nutrient cycling and food webs. The nature of these interactions can vary depending on the evolutionary context and environmental conditions in which they occur.
3. Mutually beneficial relationships can increase the populations of both species interacting. And the organisms influence their environment, shaping Earth's surface and the resources available to ecosystems. Thus, interactions among species are a major component of how like on Earth persists and evolves through time.
