Which is an adverse effect of a negative-growth population trend?
question 20 options:

an excess burden on global natural resources

inadequate financial resources to care for children

too few jobs to support a large, young population

too few workers to support an aging population

too few workers to support an aging population

Explanation:

According to nature, the cells reach a phase where most of the resources are exhausted in the body and aging kicks in. An increase in aging population would adversely affect the trend of population growth since most of these people are not able to work, look after themselves and therefore would require workers to look after them. When there are few worker to support the aging population, the population is affected because some  of them die due to starvation and emerging diseases.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
