Options

A. `T_1`
B. `T_2`
C. `T_3`
D. `T_4`

Answer

To determine in which trophic level of a terrestrial ecosystem, such as a forest, maximum energy can be found in organisms, we can follow these steps:

### Step 1: Understand Trophic Levels
- Trophic levels represent the position of organisms in a food chain. They are categorized as follows:
1. **First Trophic Level (Producers)**: These are organisms that produce energy through photosynthesis, such as plants and trees.
2. **Second Trophic Level (Herbivores)**: These organisms consume the producers. Examples include deer and goats.
3. **Third Trophic Level (Carnivores)**: These organisms eat herbivores. An example is wolves.
4. **Fourth Trophic Level (Top Carnivores)**: These are the apex predators that feed on other carnivores.

### Step 2: Energy Transfer in Trophic Levels
- Energy transfer between trophic levels is inefficient. According to the 10% rule:
- Only about 10% of the energy from one trophic level is passed on to the next level.
- This means that 90% of the energy is lost, primarily as heat.

### Step 3: Analyze Energy Distribution
- Since the first trophic level consists of producers, they have the highest amount of energy available.
- As energy is transferred from producers to herbivores (second trophic level), and then to carnivores (third and fourth trophic levels), the amount of energy decreases significantly.

### Conclusion
- Therefore, the maximum energy in a terrestrial ecosystem such as a forest is found in the **first trophic level**, which consists of producers.

### Final Answer
- **The maximum energy can be found in the first trophic level (Producers).**
