Photosynthesis is the most abundant form of anabolic metabolism in life.

Answer

### Step-by-Step Solution:

1. **Understanding Photosynthesis**:
- Photosynthesis is a process used by plants, algae, and some bacteria to convert light energy (usually from the sun) into chemical energy stored in glucose (a sugar). This process occurs mainly in the chloroplasts of plant cells.

2. **Defining Anabolic Metabolism**:
- Anabolic metabolism refers to the set of metabolic pathways that construct molecules from smaller units. These reactions require energy, and they are essential for building the components of cells, such as proteins and nucleic acids.

3. **Photosynthesis as Anabolic Metabolism**:
- During photosynthesis, plants take carbon dioxide and water and, using sunlight, convert these into glucose and oxygen. This process is anabolic because it builds larger organic molecules (glucose) from smaller ones (carbon dioxide and water).

4. **The Role of Energy**:
- The energy required for this anabolic process comes from sunlight. Thus, photosynthesis is not only a means of producing food for the plant but also a way of capturing and storing energy in a form that can be used by the plant and other organisms.

5. **Conclusion**:
- Since photosynthesis is the primary method by which plants synthesize organic compounds (like glucose) from inorganic substances (like carbon dioxide and water) using light energy, it is indeed the most abundant form of anabolic metabolism in life. Therefore, the statement is true.

### Final Answer:
The statement "Photosynthesis is the most abundant form of anabolic metabolism in life" is true.
