Answer:
Competition
Explanation:
Competition occurs when many organisms are in search for the same, limiting resource this include food, water,space.
The use of this limited resource by one species decreases availability to the other population especially when there is an increase in population the rate of competition is very high.
Competition reduces the fitness of all the organism and can either be interspecific which is among the same organisms or between different species.
Blood is essential for many organisms, such as humans and animals, for its important function of transporting substances (food, oxygen), vitamins, waste (carbon dioxide), hormones, etc. to all tissues and cells of the body.
1) Blood volume
If the blood volume increases ==> the blood flow increases.
2) Viscosity of blood
If we have an increase in blood viscosity ==> we have a decrease in blood flow
3) Peripheral Resistance
If there is an increase in peripheral resistance ==> the blood flow decreases
4) Diameter of blood vessels
If we have an increase in diameter of
blood vessels ==> decreased peripheral resistance ==> increased blood flow
5) Blood pressure
If the blood pressure increases ==> the blood flow increases.
6) In case of diseases
In the case of atherosclerosis or acute coronary syndrome ==> blood flow decreases.
7) Physical excercises:
During physical exercises ==> the heart rate increases ==> the blood flow increases.
