1. plants capturing carbon dioxide from the atmosphere would be an example of

Explanation:

Question 19:

World hunger is environmental as food production is global but resources (like land, water, fertilizers) for it are unevenly distributed. Option A matches this logic. Options B (agriculture in all nations), C (fresh water for irrigation isn't the main env link to hunger), D (fertilizer availability isn't the key env reason) are incorrect.

Ecosystem services are benefits ecosystems provide, like plants capturing CO₂ (a regulating service). Sustainable development is about balance, environmentalism is advocacy, throughput is about flow. So capturing CO₂ is an ecosystem service (Option C).

Answer:

A. Food production is global but the resources are unequally distributed.
