Cell theory meets the definition of a theory because it's been tested over a long period of time, and scientists have plenty of evidence to support this theory.

However, it doesn’t seem to meet the criterion of a scientific law. Scientists only know about life on this planet, so the theory may not be universal if life is found on other planets. In addition, scientists don’t have much data on the earliest forms of life on Earth.

Hope to help :)

Explain how seasonal fires benefit grassland ecosystems.

Although we tend to think of fires as a human invention that kills plants, animals, people, fire, as with rain or wind, is an essential natural component, basic to maintain the planet's biodiversity.

As for example, grassland ecosystems are also benefited by the same fires that allow renewal, and generate natural sustainability on the earth through the carbon cycle.
