Question

Construct at least two possible hypotheses for the student’s experiment
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 help the student find the answer to his question.

Answer 1

1. compost pits and use manure as well as bio gas can be produced

2. using natural compost may or may not help in the small run but replenishes the soil fertility in the long run unlike the artificial fertilisers

Answer 2

Answer: Utilizing natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer.

Explanation:

• Organic materials and fertilisers enhance soil texture, enabling it to retain water for longer periods of time, and boost microbial and fungi activity.
• They thereby benefit the earth in addition to helping your plants. On the other side, synthetic fertilisers rob the soil of its nutrients, rendering it useless.
• When applied appropriately, fertilisers made of organic materials benefit soil and plants alike and, in most cases, won't burn or harm plants.
• Organic fertilisers encourage advantageous soil microbes and enhance soil structure.
• Organic fertilisers are significantly safer to use because they are less concentrated than synthetic fertilisers.
• The greatest fertilisers for plants and crops in greenhouse farming are organic fertilisers because they are ecological, ecologically friendly, and non-toxic by nature.

Hence, natural fertilizer will cause the plant to grow  faster and taller than artificial fertilizer.
