Answer:
The pumping of the heart involves the alternate contraction and relaxation of the chambers of the heart. The upper chambers of the heart are called at atria and the lower chambers of the heart are called ventricles.
Answer:
Both depends on one another.
Explanation:
Yes, there is a direct relationship between the number of pollinating plants and the number of honeybees because honeybees are insects that are responsible for pollination in the flowering plants. The population of flowering plants also has a great effect on the survival of honeybees because these flowering plants provides food in the form of nectar on which these honeybees survive and make honey from it. So we can say that both flowering plants and honeybees depends on one another for the successful growth and development.
Biomass is the total mass of a specific organism in the area. If there is a negative value of change in shoot biomass, that mean the mass of the shoot in this period are less than before. This indicate increases in predation/death which reduce the population of the shoot more than its growing rate. The cause could be an increases in predator population or decreases in food/resource.
