How does the population growth curve of humans compare with that of bacteria on a petri dish?

The current population of humans is growing at a rapid rate and not indicating it is slowing down to a carrying capacity. Bacteria exhibit this type of growth when growing in a petri dish in a lab.

What is the greatest crisis ever faced by humans?
human population growth
What is a population of organisms that is cared for by humans?
A captive population.
What is pessimist view on population growth?
The pessimistic viewpoint on population growth is that they think that a population which has a high growth rate will put a strain on resources. They believe that there will not be enough resources to be able to supply the large population. ________ Population pessimism remains associated with Thomas Malthus, who warned in 1798 that humans would tend to multiply their numbers while resources available for their upkeep were limited, resulting in susbsistence crisis. This failed to happen in the 19th and 20th centuries as both global population and living standards rose at an increasing rate, though some countries suffered periodic famine as had happened in past centuries. The rate of world population increase is now falling, but it is likely to take a century for growth to end. Pessimists today fear that this slowdown will be too little and too late to prevent catastrophic ecological and resource crisis, while optimists hope that reduced fertility and technological advance will allow a "soft landing" and avert disaster.
What are general factors that affect population growth?
Resources relative to the population, e.g. food, clean water, air Threats relative to the population, e.g. presence of predators, disease, or environmental dangers Reproductive effectiveness: how many offspring does each couple have, and do the offspring correctly fabricated (not too many genetic mutations) so they are survivable. Presence of another species that wants the population to survive. For example, ants sometimes keep aphids as a source of food. Perhaps more close to home, humans keep a population of cows as a food source.

What is the greatest crisis ever faced by humans?

Why does bacterial growth depend on moisture?
Bacteria ,like humans, are made mostly of water. No water, no life (or growth).
What demographic trends have major effects on population growth rates in humans?
Factors such as declining fertility rates, increasing life expectancy, and urbanization are having significant effects on population growth rates in humans. Other factors can include migration patterns, access to healthcare, and changing societal norms around family size. These demographic trends can influence population dynamics in terms of age structure, dependency ratios, and overall population size.
How does a microbes biomass compare to a human population biomass?
Microbes outweigh humans by 5,032 to 1!
Why does a population that experiences exponential growth have a high chance of having a population crash?
The problem with human population growth is that it is more complicated than it would be if humans were not able to adjust birth rate and modify their environment.
Where is the humans greatest growth populations occurring?
The greatest growth populations of humans are currently occurring in Africa, particularly in countries such as Nigeria, Ethiopia, and the Democratic Republic of Congo. These regions have high birth rates, improving healthcare and living conditions, and a relatively young population, contributing to rapid population growth.
What is the best temperature range for medical bacterial growth?
It depends on what the bacteria is. If it is a bacteria that infects humans, then a temperature of 36-38 degrees C. Some bacteria like cold temperatures and some will grow in hot springs.
How does bacteria affect human health?
Some bacteria are beneficial to humans, and some bacteria are harmful to humans.
What are limiting factored for humans?
Control of population growth is based upon limiting factors and population interactions in each ecosystem. These are resources such as food, water, oxygen, and space availability.
These statements about bacteria and humans is false?
Humans should try to be bacteria free.
How are monerans helpful to humans?
monerans are helpful to humans because it is bacteria and bacteria helps humans by making milk yogurt
How did Thomas Malthus define 'exponential growth'?
Exponential growth states that if the population of humans kept on growing at the same rate unchecked, there would be insufficient living space sooner or later.
