Which statement is correct about the mass of carbon dioxide used during photosynthesis? A) It is equal to the total mass of oxygen used. B) It is less than the total amount of glucose and water used. C) It is equal to the total mass of glucose and oxygen form. D)It is less than the total mass of glucose and oxygen form

D) It is less than the total mass of glucose and oxygen formed.

Explanation: During photosynthesis, six molecules of water reacts with six molecules of carbon dioxide to form one molecule of glucose and six molecules of oxygen. The balanced equation for the reaction is 6H2O + 6CO2 --> C6H12O6+ 6O2.

In writing chemical equations, the mass of the reactants must be equal to the mass of the products because according to the law of conservation of mass states that matter can neither be created nor be destroyed in an ordinary chemical reaction. The mass of carbon dioxide and water must be equal to the mass of glucose and oxygen formed. Therefore, the mass of carbon dioxide used during photosynthesis is less than the mass of glucose and oxygen formed.

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.
