An ecosystem is a region where a bubble of life is created by plants, animals, and other organisms interacting with the weather, environment, and other factors. Abiotic variables, or nonliving components, coexist with biotic components in ecosystems.

Every living organism, including humans, participates in these intricate webs of interconnected relationships known as ecosystems. Healthy ecosystems maintain our soil, clean our air, control the climate, recycle nutrients, and give us food.

The interactions between species and the environment produce a natural ecosystem. An ocean, for instance, is categorized as a marine ecosystem since it contains algae, consumers, and decomposers. This kind of ecosystem goes through a cycle that starts with algae producing energy through photosynthesis.

Hence, the correct answer is option C.

The statement which summarizes the reason why the United States is one of the most ethnically diverse countries in the world is: B. People migrate to the United States from all over the world for economic opportunities and political freedoms that they may not have in their own countries.

Explanation:

Deng Xiaping's reforms aimed to bring more economic freedom to China.

What is Deng Xiaoping?

Deng Xiaoping was a Chinese revolutionary leader, military commander and statesman who served as the paramount leader of the People's Republic of China from December 1978 to November 1989. After Chinese Communist Party chairman Mao Zedong's death in 1976, Deng gradually rose to supreme power and led China through a series of far-reaching market-economy reforms earning him the reputation as the "Architect of Modern China".

He contributed to China becoming the world's second-largest economy by nominal GDP in 2010. Born in the province of Sichuan in the Qing dynasty, Deng studied and worked in France in the 1920s, where he became a follower of Marxism Leninism and joined the Chinese Communist Party in 1924.

In early 1926, Deng traveled to Moscow to study Communist doctrines and became a political commissar for the Red Army upon returning to China. In late 1929, Deng led local Red Army uprisings in Guangxi.
