Question

what is the relationship between ecological sustainability and food production?
clearing ecosystems creates more farmland and increases biodiversity that is helpful for developing disease - resistant crops.
clearing ecosystems creates more farmland but reduces biodiversity that is helpful for developing disease - resistant crops.
clearing ecosystems creates less farmland but increases biodiversity that is helpful for developing disease - resistant crops.
clearing ecosystems creates less farmland and reduces biodiversity that is helpful for developing disease - resistant crops.

Explanation:

To determine the correct relationship, we analyze each option:

• Clearing ecosystems (like forests or natural habitats) typically converts that land into farmland, so it increases farmland (eliminating options with "less farmland").
• However, clearing ecosystems destroys natural habitats, which reduces biodiversity (since many species lose their homes). Biodiversity is important for developing disease - resistant crops (e.g., through genetic diversity in wild relatives of crops). So clearing ecosystems reduces this beneficial biodiversity.

The first option says clearing increases biodiversity, which is incorrect. The second option correctly states that clearing creates more farmland but reduces biodiversity (which is helpful for disease - resistant crops). The third and fourth options have incorrect statements about the amount of farmland created.

Answer:

B. Clearing ecosystems creates more farmland but reduces biodiversity that is helpful for developing disease - resistant crops. (Note: Here we assume the options are labeled A, B, C, D in the order they appear, with the second option being B. If the original question had different labeling, adjust accordingly.)
