The Sun provides energy for plants through photosynthesis, which forms the base of the food chain and supports nearly all life on Earth.
A nail rusting is a chemical change because it forms a new substance (iron oxide). Melting, boiling, and breaking are physical changes, as they do not change the substance's chemical structure.
During photosynthesis, plants take in carbon dioxide and water and, using sunlight, produce glucose and oxygen, which is released into the atmosphere.
The crust is the outermost layer of Earth, composed of solid rock, and includes both continental and oceanic regions.
Roots anchor the plant in the ground and absorb water and nutrients from the soil, which are vital for the plant’s growth and survival.
