Answer:
When the number of organisms in an ecosystem exceeds the carrying capacity, the population will decrease.
Please see the explanation!
Explanation:
The maximum that can be maintained forever is the concept of "carrying capacity." This can only be rationally understood as the highest number that can be maintained using exclusively renewable resources. It can only be exceeded by using resources more quickly than they can be replenished.
The population gets wiped out (not by old age mortality) back to the number that can be maintained using only renewable resources when those resources become limited, as they must by definition.
Remember that every population is trying to expand, therefore if a species finds a resource that it can use more quickly than it replenishes, the population will undoubtedly expand to use that newly discovered capability. Another way to put this is to say that when the species average is x newborns and the subsistence supply is steady, (x-2)/x children must perish. Less offspring must perish than the formula predicts when the species finds a new non-renewable source of food, increasing the subsistence supply.
It should be noted that there are plainly too many people in the world. Over the past few hundred years, we have developed various technologies that have increased subsistence extraction and decreased waste. Of course, we have multiplied to occupy that additional space. In order to provide enough food to sustain 7+ billion people at once, we need fossil fuels and a number of other resources that do not replenish as quickly as we use them. The last time humanity were able to maintain their population on exclusively renewable resources, there were less than 1 billion people. Be aware that we have never been able to raise subsistence production as quickly as we have sought to increase our population. We have always had an average of too many infants, as seen by the starvation-related child mortality that affects some populations.

A hole in the skin caused platelets to rush to the site and release a chemical that releases more platelets. This is an example of what type of mechanism
A hole in the skin caused platelets to rush to the site and release a chemical that releases more platelets. This is an example of a positive feedback mechanism.
Positive feedback mechanism:When a variable is changed, there is a response that leads to further change in the same direction, which is known as positive feedback.
An illustration can be used to explain positive feedback. Positive feedback aids in the quick creation of a platelet plug in a damaged blood artery when we cut our fingers. Platelets are drawn to the wounded location, and as they accumulate, they each release chemicals that draw additional platelets.
In order to stop excessive blood loss, numerous platelets quickly collect and work together to seal the damaged blood vessel's hole.
Positive feedback mechanisms are demonstrated by the posterior pituitary gland's production of oxytocin during labor. The muscle contractions that force the infant into the delivery canal are induced by oxytocin.

How do the continental coastlines support the Theory of Continental Drift (Pangaea Theory)?
Explain how fossil distribution supports the Theory of Continental drift.
How do distinctive rock strata support the Theory of Continental Drift?
Honor Biology:
How does coal distribution support the Theory of Continental Drift?
Evidence like the same type of rocks and fossils in continents separated by the ocean, continental coastlines fitting together, and the presence of coal in polar regions support the Theory of Continental Drift.
What are the tectonic plate and continental drift theories?The tectonic plates theory explains the movement of the different plates based on the crust movements.The continental drift theory explains how these plate movements have been taking place for millions of years.Alfred Wegener proposed for the first time that continents were once all together in one big continent named Pangea, and with time, they split and separated into many pieces.
Although Wegener’s theory was criticized, the geologist Du Toit published in 1937 a list of 10 pieces of evidence that would support the theory of tectonic plates and continental drift.
What is the evidence that support the theories of tectonic plates and continental drift?Wegener, Du Toit, and other following researchers made use of the following list of evidence to prove these theories,
Gondwana glaciation evidence,
Lithological and structural evidence
Sedimentary layers, chronologically deposited, reflect history through their composition.
The same type of rocks of similar age express the same chronological deposition in continents currently separated by the ocean.
This fact also suggests that continents were once together and these rocks formed simultaneously in the same place.
Plates fitting together
Continental coastlines seem to fit with each other. For instance, the South American coastline seems to fit perfectly with the African coastline.
Paleontological evidence. Fossil distribution.
Plant and animal fossils distributed in different continents in the same sedimental layers suggest that these land masses were once together composing a big unique continent.
When reconstructing the supercontinent, the areas in which these fossils were found get together in the same supercontinental region.
Finding the same fossils in the same sedimental layers suggests that these continents were once together, and these organisms used to live in the same region.
Coal distribution
Since coal gets formed under warm to hot and humid climatic conditions, it is suggested that coal found in Antarctic areas and other regions near the poles, was formed when the continents were together near the equatorial region.
How do the continental coastlines support the Theory of Continental Drift (Pangaea Theory)?
Because continental coastlines fit together. For instance, South America and Africa.
How fossil distribution supports the Theory of Continental drift?
Because the same fossils are found in the same sedimental layers of continents separated by the ocean.
How do distinctive rock strata support the Theory of Continental Drift?
Because the same type of rock of the same age are found in the same sedimental layers of continents separated by the ocean.
How does coal distribution support the Theory of Continental Drift?
Because the coal found under Antarctica and other polar regions must have formed in warmer and more humid areas, such as the Equator, suggesting plate displacement.

what is the source of mold on bread
Answer:
Well, mold develops and grows eventually forming a colony due to spores landing on the bread and multiplying, hence growing the mold.
Where does mold on bread come from?
On bread, molds (many colonies of various sorts) develop from microscopic fungi that float in the atmosphere.
The fungus that causes mold develops as extremely little filaments called hyphae, which enable the fungus to float and be transported by the air. The hyphae spread by forming an apparent, hairy network when they land on bread or other organic materials. The color of the spores that develop on the end of the hyphae determines the color of the mold network .There are molds that grow as single-cell spores as opposed to mold that grows as multicellular hyphae with a spore at the end. They are known as yeast.
