Explanation:

Question 12

• Option a is wrong because the goal isn't to have only annuals survive.
• Option b is wrong as perennials can produce seeds.
• Option c is wrong because competition between species can't be completely eliminated, and it's not the main reason for choosing the mix.
• Option d is correct as annuals and perennials together provide biodiversity, and perennials return each year, which is important for prairie restoration.

• Option a describes a perennial plant.
• Option b is not the characteristic of a biennial plant.
• Option c accurately describes a biennial plant's life cycle: it grows leaves in the first year, flowers and produces seeds in the second year, and then dies.
• Option d describes an annual plant.

Answer:

d. To provide biodiversity and ensure some plants return each year
