- A tree is a kind of plant
- A redwood tree is a kind of tree
- A giant redwood tree is a kind of redwood tree
- So, a giant redwood tree is a kind of plant

- A giant redwood tree is a kind of plant
- Green plants perform photosynthesis to get food
- Hence, the giant redwood tree would perform photosynthesis to get food

- The giant redwood tree would perform photosynthesis to get food
- Photosynthesis means green plants convert solar energy to food
- Therefore, the giant redwood tree performs photosynthesis to get food by converting solar energy to food

- The giant redwood tree performs photosynthesis to get food by converting solar energy to food
- Food is a kind of chemical energy
- Therefore, the giant redwood tree performs photosynthesis to get food by converting solar energy to chemical energy

Hence, the giant redwood tree performs photosynthesis to get food by converting solar energy to chemical energy
