Answer:

B. Mutualistic

Explanation:

Cattle egret and grazing cattle exhibit close association. Egrets always forage close to the grazing cattle since the cattle stir up the vegetation while moving. This flushes out the insects from the vegetation and egrets feed on them. Without a grazing cattle, egrets find it difficult to locate and catch the insects. Since egrets are benefited from the association, it is mutualism.

Temperatures are rising world-wide due to greenhouse gases trapping more heat in the atmosphere.

• Droughts are becoming longer and more extreme around the world.

• Tropical storms becoming more severe due to warmer ocean water temperatures.

• As temperatures rise there is less snowpack in mountain ranges and polar areas and the snow melts faster.

• Overall, glaciers are melting at a faster rate.

• Sea ice in the Arctic Ocean around the North Pole is melting faster with the warmer temperatures.

• Permafrost is melting, releasing methane, a powerful greenhouse gas, into the atmosphere.

• Sea levels are rising, threatening coastal communities and estuarine ecosystems.
