The technique of using live organism or enzymes from organisms to produce products and processes useful to humans.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for a technique that involves using live organisms or their enzymes to produce products and processes that are beneficial to humans.

2. **Identifying the Key Term**: The key term here is "biotechnology." This term encompasses the use of biological systems, living organisms, or their derivatives to create or modify products for specific uses.

3. **Examples of Biotechnology**:
- **Baking**: In the baking industry, yeast (a living organism) is used to ferment dough, which helps in the production of bread. The yeast converts sugars into carbon dioxide and alcohol, causing the dough to rise.
- **Vaccines**: Vaccines are another example where live organisms or their components (like proteins or toxins) are used to stimulate the immune system to provide immunity against diseases.

4. **Conclusion**: Based on the definition and examples, the technique described in the question is best identified as "biotechnology."

**Final Answer**: The technique of using live organisms or enzymes from organisms to produce products and processes useful to humans is called **biotechnology**.
