These interactions are critical for the flow of energy, cycling of nutrients, and maintenance of life-supporting processes, all of which are profoundly influenced by climate change.

### Structure of Ecosystem

The structure of an ecosystem refers to the physical organization and arrangement of its components, both living and non-living. It can be broadly divided into biotic components and abiotic components.

#### Biotic Components

Biotic components are the living organisms in an ecosystem, classified into three major categories based on their roles:

1. Producers (Autotrophs): These are primarily photosynthetic organisms like green plants, algae, and some bacteria that convert solar energy into chemical energy through photosynthesis.
