- Food is a source of energy for plants
- Green plants are a kind of producer
- Hence, food is a source of energy for producers

- Food is a source of energy for producers
- One can get something from a source
- Therefore, producers can get energy from food

- Green plants provide food for themselves / animals / consumers by performing photosynthesis
- Making something is a kind of method for providing something
- Hence, green plants make food by performing photosynthesis

- Photosynthesis is a kind of chemical process
- If a living thing requires something for a process then that living thing uses that something for that process
- Therefore, if a living thing requires something for photosynthesis then that living thing uses that something for photosynthesis

- If a living thing requires something for photosynthesis then that living thing uses that something for photosynthesis
- A plant requires sunlight for photosynthesis
- A plant is a kind of living thing
- Therefore, a plant uses sunlight for photosynthesis

- A plant uses sunlight for photosynthesis
- Green plant is a kind of plant
- Therefore, green plant uses sunlight for photosynthesis

- Green plants make food by performing photosynthesis
- Green plant uses sunlight for photosynthesis
- Hence, a green plant uses sunlight to make food

- If a thing uses something that comes from a source then that thing uses the source of that something
- The sun is the source of solar energy called sunlight
- So, if a thing uses sunlight then that thing uses the sun

- A green plant uses sunlight to make food
- If a thing uses sunlight then that thing uses the sun
- Therefore, a green plant uses the sun to make food

- A green plant uses the sun to make food
- Green plants are a kind of producer
- Hence, a producer uses the sun to make food

- Food is a source of energy for producers0
- Producers can get energy from food
- So, producers get energy by using the sun to make food

Therefore, producers get energy by using the sun to make food
