Orgenisms which systhesise carbohydrates from inorganic compounds using radiant energy are called

Options

A. decomposers
B. producers
C. herbivores
D. carnivores

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about organisms that synthesize carbohydrates from inorganic compounds using radiant energy.

2. **Identifying the Process**: The process of synthesizing carbohydrates, particularly glucose, involves using inorganic compounds such as carbon dioxide and water.

3. **Recognizing the Source of Energy**: Radiant energy in this context refers to light energy, which is primarily sunlight.

4. **Identifying the Organisms**: The organisms that perform this synthesis are primarily plants, which use sunlight, carbon dioxide, and water to create glucose through a process called photosynthesis.

5. **Defining Photosynthesis**: Photosynthesis is the process by which plants convert light energy into chemical energy stored in carbohydrates, releasing oxygen as a byproduct.

6. **Categorizing Organisms**: In ecological terms, plants are known as producers because they produce their own food and serve as the base of the food chain.

7. **Selecting the Correct Answer**: Given the options (decomposers, producers, herbivores, carnivores), the correct answer is "producers" since they are the ones that synthesize carbohydrates from inorganic compounds using radiant energy.

**Final Answer**: Organisms that synthesize carbohydrates from inorganic compounds using radiant energy are called **producers**.
