The correct answer is C. Because plants (mainly the aquatic plants) cannot release oxygen in a very low or high temperature. So the graph at C is right as it shows that aquatic plants release less oxygen in both low and high temperatures

its wrong as minerals are to be taken in least quantity ,far less than proteins and fat.Kindly rectify the mistake,mineral should have been last in order.

Ans 4:

Class : Class 5
Minerals are considered as micronutrients whereas carbohydrates, protein and fats are macronutrients so they should be taken in higher quantities

Ans 7:

Class : Class 8
Master Answer- Carbs such pizzas and burgers are very harmful for us. So,they should be consumed in the least amount. Minerals are micronutrients so they should be consumed in less amounts. Fats give us energy so they must be consumed in high quantities. Proteins build our muscles and should be consumed in higher quantities. thus, option D.

Ans 8:

Class : Class 8

Ans 9:

B

Ans 10:

Class : Class 5
i thought A is the correct option pls clarify !

Ans 11:

Class : Class 5
It was a little tricky for me also

Ans 12:

Class : Class 9
The correct answer is B as our body needs carbohydrates in maximum quantiuty as they give us energy

Ans 13:

Class : Class 5
BB!!!

Ans 14:

Class : Class 7
carbs, proteins and fats are macronutrients so they should be more than minerals which is a micronutrient but there is no such answer
