Many farmers and gardeners compost their plant and animal waste. the living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. the next season, farmers use this substance as a natural fertilizer for their crops. a biology student has grown tomato plants for several years. until now, he used an artificial fertilizer formulated for tomato plants. this fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. the student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer. answer the following questions to plan an investigation using the steps of the scientific method and the student find the answer to his question. part a what are the student’s observations and inferences before he starts his investigation?

The student's observations before he starts his experiment are that his tomato plants grew faster and taller with his artificial fertilizer rather than without any fertilizer at all.

The student has observed That artificial fertilizer makes his plants grow faster and taller than plain soil. He knows that compost is a natural fertilizer. So, he infers that compost will make his plants grow faster then they grow in plain soil. that artificial fertilizer makes his plants grow faster and taller than plain soil. He knows that compost is a natural fertilizer. So, he in first that compost will make his plants grow faster than they grow in plain soil
