Question

question 45
grasslands are efficient at removing carbon because:
○ they are always wet
○ they have deep root systems
○ they have no plants
○ they have shallow roots

Explanation:

To determine why grasslands efficiently remove carbon, we analyze each option:

• "They are always wet" is incorrect as grasslands are typically not always wet (e.g., temperate grasslands have seasonal moisture).
• "They have deep root systems" is correct. Grassland plants (like grasses) have deep roots that store carbon in the soil and help sequester it.
• "They have no plants" is wrong because grasslands are defined by grassy vegetation.
• "They have shallow roots" is incorrect; deep roots are key for carbon storage in grasslands.

Answer:

B. They have deep root systems (assuming the option "They have deep root systems" is labeled as B; adjust the identifier based on the actual option numbering in the question, but the text is "They have deep root systems").
