1. sugar beets plants start from tiny seeds and grow to be large plants. where does the bulk of their mass come from? a. nutrients absorbed from the soil b. carbon dioxide taken in from the surrounding air c. sugars absorbed from the soil d. oxygen taken in from the surrounding air 2. in what part of the beet pant is the excess sucrose stored? a. root b. leaves c. stem

1.  B. carbon dioxide taken in from the surrounding air

2. A. Root

Explanation:

Sugar beet plant carries out photosynthesis and stores the excess of the sucrose in its taproots. During the process of photosynthesis, the plant absorbs CO2 from the air, water from the soil and synthesizes organic sugars in the presence of sunlight.

Atmospheric CO2 contributes carbon and oxygen atoms to the formed sugars which in turn are stored in plant parts. Therefore, atmospheric CO2 makes most of the mass of the photosynthesizing plants such as sugar beets. The taproots of beet plants are modified into storage roots to store the excess of the organic sugars.

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.
