Question

the pictures show one of earths polar ice caps in 1984 and 2012. what change in the arctic ecosystem is being shown in the pictures? a decrease in the absorption of solar radiation, leading to an increase in the thickness of the ice cap and a greater stability for migratory bird populations. an expansion of the ice cap, providing new solid surface areas that initiate the rapid development of terrestrial plant communities in previously barren zones. a reduction in the extent of the ice cap, which diminishes critical hunting grounds and breeding areas for ice - dependent species, fundamentally altering the arctic food web. a natural thinning of the ice that primarily creates more widespread open water, thereby increasing overall marine biodiversity and providing new pathways for various aquatic species to thrive.

Explanation:

Al comparar las imágenes de 1984 y 2012, es evidente que el área cubierta por hielo polar ha disminuido. Esto afecta negativamente a las especies dependientes del hielo, ya que sus áreas de caza y cría se reducen, lo que altera el ecosistema y la red alimentaria del Ártico.

Answer:

C. A reduction in the extent of the ice cap, which diminishes critical hunting grounds and breeding areas for ice - dependent species, fundamentally altering the Arctic food web.
