Cybernetic is associated with

Options

A. Flow of energy
B. Cycle of energy
C. The energy released
D. Study of energy

Explanation

**Step-by-Step Solution:**

1. **Understanding Cybernetics**: Cybernetics is a field that studies the flow of information and control in systems, particularly in biological and ecological contexts.

2. **Energy Flow in Ecosystems**: In an ecosystem, energy flows through various trophic levels, starting from producers (like plants) to consumers (herbivores and carnivores).

3. **Food Chain Example**: Consider a simple food chain:
- Grass (producer) → Deer (herbivore) → Fox (carnivore) → Lion (top predator).
- Here, the grass captures energy from the sun, which is then transferred to the deer when it eats the grass, and so on.

4. **Unidirectional Flow of Energy**: The energy flow in a food chain is unidirectional, meaning it moves in one direction—from producers to various levels of consumers. This is a key characteristic of energy flow in ecosystems.

5. **Conclusion**: Therefore, cybernetics is associated with the flow of energy in a food chain, emphasizing its unidirectional nature.

**Final Answer**: Cybernetic is associated with the flow of energy.
