Question

1.3 sustaining terrestrial ecosystems

which of the following is not a way to prevent soil erosion?

planting trees
no till farming
leaving part of the previous crop in the field

Explanation:

Analyze the question

The question asks to identify which option is NOT a way to prevent soil erosion.

Evaluate the options

• Planting trees: Tree roots bind soil particles together, and their leaves reduce the impact of raindrops, which directly prevents soil erosion.
• No till farming: This practice avoids disturbing the soil structure, leaving organic matter on the surface to protect against wind and water erosion.
• Leaving part of the previous crop in the field: This is also known as crop residue management. The leftover plant material covers the soil, shielding it from wind and rain, which helps prevent erosion.

Identify the missing or incorrect option

All three visible options are highly effective, standard methods used to prevent soil erosion in Terrestrial Ecosystems. Since the question asks for what is NOT a way to prevent soil erosion, and all listed options actually do prevent it, the correct answer choice is not fully visible in the image, or there is an implicit "None of the above" or a missing fourth option (such as intensive tillage or clear-cutting).

However, looking closely at the options provided:

1. Planting trees (Prevents erosion)
2. No till farming (Prevents erosion)
3. Leaving part of the previous crop in the field (Prevents erosion)

Since all three listed options are active conservation methods, none of these three is the correct answer to "NOT a way to prevent soil erosion." If this is a multiple-choice question where we must select from the visible options, we must note that all three listed options are indeed valid prevention methods. If a fourth option like "Tilling the soil deeply" or "Deforestation" were present, that would be the correct choice. Given the visible choices, they all prevent erosion. Let's formulate the response to clarify that all three listed options are indeed ways to prevent erosion.

Answer:

Question 1

• (A) Planting trees
• (B) No till farming
• (C) Leaving part of the previous crop in the field
