B. Originates from a center of power
C. Has a group impact across socioeconomic groups
D. Involves the spread of ideas
E. spreads slowly over a long period of time
Unlike hierarchical diffusion, contagious diffusion impacts across socioeconomic groups because it involves a concept or idea spreading without regard to social status. This is unlike hierarchical diffusion where ideas originate from a power center and trickle down to others.
Unlike hierarchical diffusion, contagious diffusion option C 'Has a group impact across socioeconomic groups' is correct. In contagious diffusion, a concept or idea spreads outwards from its source to all adjacent groups or individuals, regardless of their social status. This is different from hierarchical diffusion where ideas or concepts start with an individual or group of authority or power and then trickle down to other people. For example, a new slang term could spread rapidly through a school (contagious diffusion), regardless of social divides such as 'popular' vs. 'unpopular' students.

Ecosystems survive through earth’s changes by adapting, evolving, and maintaining biodiversity, ecological interactions, and essential resources.
Ecosystems have survived on Earth through various changes due to their ability to adapt and evolve. One of the key factors that has helped ecosystems survive is biodiversity. The presence of a wide range of species within an ecosystem increases its resilience and ability to withstand disturbances.
Additionally, ecological interactions such as symbiosis and predation play important roles in maintaining ecosystem balance. For example, certain organisms may provide mutual benefits to each other, while predators help control the population of prey species.
Furthermore, the availability of essential resources like water, sunlight, and nutrients is vital for the survival of ecosystems. These resources support the growth and functioning of organisms within the system.
