Question

1. which of the following is an example of a sustainable practice?

a. cutting down trees without planting new seedlings
b. growing and harvesting of crops that allow future crop yields
c. clearing land and making the soil unsuitable for agriculture use
d. fishing methods that will diminish the entire population of salmon

1. sustainability of organisms is dependent on the ability of the organisms to

a. obtain nutrients.
b. grow and develop.
c. migrate to different habitat.
d. pass on their genetic information to future generations.

Explanation:

• Question 6:
• Sustainable practice means a method that can be maintained over time without depleting resources.
• Option A: Cutting down trees without replanting depletes forest resources, not sustainable.
• Option B: Growing and harvesting crops that allow future yields is sustainable as it ensures resource availability.
• Option C: Clearing land and making soil unsuitable for agriculture destroys agricultural resources, not sustainable.
• Option D: Fishing methods that diminish salmon population deplete fish resources, not sustainable.
• Question 7:
• Sustainability of organisms in an ecological context is about the long - term survival of the species.
• Option A: Obtaining nutrients is a short - term survival need, not directly related to species sustainability.
• Option B: Growth and development are part of an organism's life cycle but not the key to species sustainability.
• Option C: Migration is a behavior for some organisms but not the core of species sustainability.
• Option D: Passing on genetic information to future generations ensures the continuation of the species, which is crucial for sustainability.

Answer:

1. B. growing and harvesting of crops that allow future crop yields
2. D. pass on their genetic information to future generations
