The highest trophic level in a food chain is often shown as literally being the highest in the diagram. Although this food chain is set up differently, you can still tell that the hawk is the highest trophic level because all the arrows point in its direction.
We can observe physical properties of elements and compounds without changing the substance.
Examples of physical properties: Density, color, boiling point, state of matter, appearance: dull or shiny, etc.
But we can also observe and measure chemical properties by reacting a substance with something else. For example, like mixing baking soda and vinegar together. The vinegar reacts with the baking soda and produces carbon dioxide: a new substance.
Some examples of chemical properties: Flammability, amount of heat that is released during combustion, toxicity (how much damage it causes to other organisms), radioactivity, and ability to oxidize (when you have metal that becomes rusty looking).
Chemical changes is all that which occurs with the formation of new substances.
Physical changes are all the transformations of matter without altering its chemical composition occurs. Is any phenomenon that occurs without the formation of new substances.
hope this helps!
