Question

farms.
which three effects will this management practice likely have on the area?
a. reduced biodiversity
b. increase in storm water runoff
c. long - term increase in soil productivity
d. decreased availability of mineral resources
e. short - term increase in carbon dioxide emissions

Explanation:

The problem involves environmental changes (like land use change from the satellite images) and their ecological impacts. Let's analyze each option:

• Option A: If the land use changes (e.g., deforestation or conversion to agriculture), habitats are destroyed, so biodiversity reduces. This is a likely effect.
• Option B: With less vegetation (from land change), storm water runoff increases (since plants absorb and slow water). This is likely.
• Option C: Long - term soil productivity: If land is mismanaged (like over - farming), soil productivity might decrease. But if we assume sustainable management, no. However, the other options are more direct. Wait, maybe the management practice is bad. But let's re - evaluate. Wait, the satellite images show a change from more forested (top) to more fragmented (bottom, maybe agriculture). So:
• Reduced biodiversity (A): Correct, as habitats are broken.
• Increase in storm water runoff (B): Correct, less vegetation to hold water.
• Short - term increase in CO₂ (E): If trees are cut, they release CO₂, so short - term CO₂ increases. Wait, the question is which three. Wait, maybe I misread. Wait the options are A, B, C, D, E. Wait the question is "Which three effects...". Let's re - check:
• A: Reduced biodiversity: When natural ecosystems are converted (like to farms), species lose habitats, so biodiversity reduces. Correct.
• B: Increase in storm water runoff: Vegetation intercepts rain, reduces runoff. Without it, runoff increases. Correct.
• E: Short - term increase in carbon dioxide emissions: If trees are removed (deforestation for farming), the stored carbon is released, leading to short - term CO₂ increase. Correct.
• C: Long - term increase in soil productivity: Usually, converting natural land to agriculture (especially if not managed well) leads to soil degradation (loss of nutrients, erosion), so long - term productivity would decrease, not increase. So C is incorrect.
• D: Decreased availability of mineral resources: Mineral resources are not directly affected by this land use change (agriculture vs forest). So D is incorrect.

So the three correct options are A, B, E. But maybe the intended answer is A, B, and another. Wait, maybe I made a mistake with E. Wait, if the management practice is, say, afforestation, but the images show the opposite (more cleared land). So cutting trees releases CO₂, so E is correct. So the three effects are A, B, E.

Answer:

A. reduced biodiversity, B. increase in storm water runoff, E. short - term increase in carbon dioxide emissions
