Smaller food chains are more efficient as compared to larger ones. Why ?

Explanation

**Step-by-Step Solution:**

1. **Understanding Food Chains**: A food chain represents the flow of energy and nutrients from one organism to another in an ecosystem. It consists of various trophic levels, starting from producers (like plants) to primary consumers (herbivores), secondary consumers (carnivores), and so on.

2. **Definition of Small and Large Food Chains**: Smaller food chains have fewer trophic levels, meaning there are fewer organisms involved in the transfer of energy. In contrast, larger food chains have more trophic levels, which means more organisms are involved.

3. **Energy Transfer in Food Chains**: Energy transfer between trophic levels is not 100% efficient. Typically, only about 10% of the energy from one level is passed on to the next. This means that as you move up the food chain, the amount of energy available decreases.
