During exhalation, your respiratory muscles contract to push air out of your lungs.
Your respiratory muscles contract each time you exhale.
When you exhale, the primary muscle responsible for this action is the diaphragm, which contracts and moves upwards, reducing the volume of the lungs and forcing air out. Additionally, the intercostal muscles, located between the ribs, also contract and help in the process of exhalation.
In summary, your respiratory muscles contract during exhalation to push air out of your lungs.

Answer:
Exothermic reactions
Explanation:
Exothermic reactions are more spontaneous because they release energy for example "my bouncy ball is rolling down the hill".
Exothermic reactions tend to occur spontaneously as they release energy in the form of heat or light.
The type of chemical reaction that tends to occur on its own, or spontaneously, is called an exothermic reaction. In an exothermic reaction, energy is released in the form of heat or light. This release of energy makes the reaction more favorable and allows it to occur without the need for external energy input.
One example of an exothermic reaction is the combustion of gasoline. When gasoline reacts with oxygen, it releases a large amount of energy in the form of heat and light, causing the gasoline to burn.
Another example is the reaction between sodium and water. When sodium reacts with water, it produces sodium hydroxide and hydrogen gas, along with a release of energy. This reaction is highly exothermic and can even cause the hydrogen gas to ignite.

Answer:Long term drought, change of season from winter to summer, forest fire are unfavorable environmental factors which can deplete the amount of resources already available with the ecosystem. The long term drought will be a condition in which the ecosystem will suffer from non-availability of water.
