Practise This Question

Bholu wants to grow plants inside his house but he does not like the mess soil makes. So, Bholu uses a technique called hydroponics. In this technique, plants are grown without soil and instead receive nutrients from mineral rich water that is made to flow over the plants roots as shown below. The water needs to be dissolved with chemicals containing plant nutrients such as containing nitrogen, potassium and zinc.

Choose the option that best depicts the relative amount of nutrients that needs to be added to the water. (A bigger circle means more amount and vice versa; if a circle is not present it means that the nutrient is not added ).
