Question

A farmer has sown seeds in his field, after sometime the seeds have grown into a crop. What kind of change is growing of seeds into a crop, is it man made or natural. Explain

Answer 1

Growing of seeds into a crop is a man made change since the man has brought the seeds and sown them to grow in a particular manner.
Man made changes are the changes that are done by man on naturally occuring things.
If a plant grows by itself naturally, then it is called a natural change.
