No, it's not true that all plants make food in the same way. While most plants use photosynthesis to make food, some plants have adapted different methods to obtain energy.

Here's a breakdown:

Photosynthesis:

* This is the most common method, where plants use sunlight, water, and carbon dioxide to create glucose (sugar) as their energy source.

* They have chlorophyll, a green pigment, which absorbs sunlight for this process.

Other methods:

* Parasitic plants: These plants don't make their own food. They obtain nutrients from other living plants by tapping into their vascular systems.

* Myco-heterotrophic plants: These plants rely on symbiotic relationships with fungi for their food. The fungi get their nutrients from decaying matter, and the plants extract these nutrients from the fungi.

* Carnivorous plants: These plants supplement their diet by trapping and digesting insects. They still perform photosynthesis but use the additional nutrients from insects to thrive in nutrient-poor environments.

Therefore, while photosynthesis is the most common way plants make food, there are other methods that allow some plants to survive and thrive in different environments.
