A. 1, 2

• Ecosystems are characterized by several vital functions that ensure their sustainability and productivity.

• Energy flow describes the movement of energy from the sun through various trophic levels. Production refers to the creation of organic matter.

• Decomposition is the breakdown of dead organic material, releasing nutrients.

• Nutrient cycling is the movement of chemical elements through the ecosystem.

• Ecological succession is the process of change in the species structure of an ecological community over time, often leading to a more stable and complex community, rather than degradation.
