Question

question 11 (1 point) how does understanding plant life cycles benefit agriculture?
○ a it reduces the need for pollinators
○ b it enables better selection and timing for planting and harvesting crops
○ c it discourages farmers from crop rotation
○ d it accelerates plant mutations

question 12 (1 point)
in a prairie restoration project, why is it important to choose the right mix of annual and perennial plants?
○ a to guarantee only annuals survive
○ b because perennials cannot produce seeds
○ c to eliminate competition between species
○ d to provide biodiversity and ensure some plants return each year

Explanation:

Question 11

• Option a: Understanding plant life cycles doesn't reduce the need for pollinators; many plants rely on pollinators, and this understanding doesn't change that requirement.
• Option b: Knowing plant life cycles helps farmers know when to plant (e.g., based on germination and growth stages) and when to harvest (based on reproductive or maturity stages), so this is correct.
• Option c: Understanding life cycles would likely support crop rotation (to manage soil nutrients, pests, etc.), not discourage it.
• Option d: Plant mutations are genetic or environmental changes, and understanding life cycles doesn't accelerate mutations.

• Option a: The goal of prairie restoration isn't to have only annuals survive; perennials are important for long - term ecosystem stability.
• Option b: Perennials can produce seeds (e.g., many perennial flowers and grasses produce seeds), so this is incorrect.
• Option c: Some competition between species is natural and even beneficial in an ecosystem; the goal isn't to eliminate competition.
• Option d: Annuals provide short - term growth and diversity, while perennials return year after year, so a mix provides biodiversity and long - term plant presence, which is important for prairie restoration.

Answer:

b. It enables better selection and timing for planting and harvesting crops
