Photosynthesis involves a chemical change.
no physical change is ptting ice cream and milk and mixing it for a milkshake or burning a piece of paper.
Ofcourse it does. All plants, algae and cyanobacteria perform photosynthesis, which is a chemical reaction. So answering your question, tree growth and for that matter all plant growth involves chemical changes.
It is a chemical changechemical change
Yes it is chemical because the sun is producing food by causing chemicals and substances
No, the process of carbon dioxide being converted into more complex molecules by plants during photosynthesis is a chemical change, not a physical change. Chemical changes involve the formation of new substances with different chemical properties, whereas physical changes only affect the physical state of a substance without altering its chemical composition.
Physical changes
Is chemicals from plants chemical weathering or physical weathering
A physical or chemical change in an organism's environment that triggers a response is referred to as a stimulus. This stimulus can cause the organism to react in a way that helps it adapt to the changed conditions, such as by moving to a different location, changing its behavior, or adjusting its metabolic processes. For example, plants may respond to changes in light levels by altering their growth patterns.
Fertilizer typically involves a chemical reaction when applied to soil. The components in the fertilizer interact with the soil and plants to provide essential nutrients for growth. Physical processes such as dissolving and diffusion also play a role in the uptake of nutrients by plants.
One common chemical change that occurs naturally in plants is photosynthesis. During photosynthesis, plants use sunlight, carbon dioxide, and water to produce glucose and oxygen. This process is essential for the plant's growth and provides oxygen for other organisms.
No, plants decaying is a chemical change because the process involves the breakdown of organic compounds within the plant material into simpler substances. This chemical decomposition results in the formation of new compounds, rather than just a rearrangement of existing particles, which is characteristic of a physical change.
