Answer 1

The answer to your riddle seems to be "photosynthesis."

- It forms the foundation of food chains (the building block).
- Photosynthesis is the process that starts the flow of energy through ecosystems (the first link).
- It converts sunlight into energy, which can be thought of as steady energy (the steady clock).
- It is essential for life in ecosystems, supporting numerous organisms (the life of an ecosystem, a mighty flock).
