In most ecosystems, large carnivores and omnivores rely heavily on carrion as a food supply. Crows, vultures, condors, hawks, eagles, hyenas, Virginia opossums, Tasmanian devils, coyotes, and Komodo dragons are some examples of carrion-eaters (or scavengers).

Numerous invertebrates consume carrion, including burying and carrion beetles, as well as flesh flies, calliphorid fly maggots (including one of the most significant species in Calliphora vomitoria), and other insects.

significance role of unemployment on economic growth in nepal


Answers

Unemployment plays a significant role in economic growth in Nepal. High unemployment rates can lead to a decrease in economic growth as it results in a reduction in the number of people participating in the labor force and a decrease in the amount of goods and services that are produced.

Unemployment can lead to a decrease in consumer spending, which can lead to a decrease in demand for goods and services. This in turn can lead to a decrease in production, which can lead to a decrease in economic growth. Additionally, unemployment can lead to a decrease in government revenue due to decreased tax revenue from people who are not working, which can further decrease economic growth.

Moreover, high unemployment rates in Nepal can also lead to social issues such as poverty, crime, and political unrest. This can create a negative feedback loop in which poor economic conditions lead to social issues, which in turn can lead to even worse economic conditions.

On the other hand, a reduction in unemployment can lead to an increase in economic growth. When more people are employed, there is more money circulating in the economy, leading to increased consumer spending, increased demand for goods and services, and increased production. This can lead to an increase in economic growth.

In summary, unemployment plays a significant role in economic growth in Nepal. High unemployment rates can lead to a decrease in economic growth, while a reduction in unemployment can lead to an increase in economic growth. Therefore, it is important for the government to take steps to address unemployment and promote job creation in order to promote economic growth in Nepal.
