The available amount of food is what is going to determine the carrying capacity. Also, carrying capacity can be dependent on the amount of shelter a system has.
Explanation:
- One of the main differences between adult and fetal circulation is <em>the direction and where the non-oxygenated and oxygenated blood circulates</em>. In adults arteries carry oxygenated blood away from the heart and veins carry non-oxygenated blood towards the heart; in fetuses, arteries carry non-oxygenated blood away from the heart and veins carry oxygenated blood back to the heart.
- Another difference is <em>where does the exchange of gases takes place</em>, in fetuses blood is oxygenated in the placenta, in adults in the lungs.
- The circulation between adults and fetuses differs in <em>where does the pressure increases</em>, in adults is on the left side of the heart, in fetuses on the right side.
- Finally,<em> another important difference between adults and fetuses is the presence of shunts</em>, in fetuses these shunts allow both sides of the heart to work parallelly letting mix blood from both ventricles. This shunt gets closed after birth, so adults do not have them.

The correct answer is that a population overshoots the carrying capacity and environmental pressures and shortfalls begin to exert their effects. A certain area of environment only has limited resources such as food, water, habitat, etc. These limited resources are called the carrying capacity of the environment. If the population exceeds the carrying capacity of the environment, there will be not enough resources to sustain the population therefore members of the population will die and the overall population number will crash hence the term <em>population crash. </em>
Answer:
When magma reaches the surface of the Earth it is called lava. Lava is molten rock that comes through a crack in the Earth's crust.
