Answer:
1. Explain why predators need to eat more than primary consumers.
Explanation:
Predators need to eat more than primary consumers because in the trophic pyramid, primary consumers are at the bottom which means they receive the most energy because they eat the plants. As the pyramid goes on upwards, energy is lost each time, so that means by the time it reaches the top of the pyramid their is only about 0.1% of the energy we started with when the primary consumers ate the producers. Meaning, the predators need to eat more than the primary consumers because although the predators eat more than the primary consumers, they still at the end of the day get the same amount of energy just one eats more than another.

Answer:
The correct option is the pKa of acetic acid or acetate.
Explanation:
The blood pH is affected by hyperventilation since it triggers hypercapnia, an increase in metabolic acids and therefore a decrease in blood pH.
Excessive consumption of sodium bicarbonate, since this would alkalize the blood, and finally, prolonged fasting or excessive hunger generates the degradation of fat sources, with the consequent formation of ketone bodies as a product, and therefore entering a metabolic acidosis.
For example, if the acceleration is zero, then the velocity-time graph is a horizontal line (i.e., the slope is zero). If the acceleration is positive, then the line is an upward sloping line (i.e., the slope is positive). ... If the acceleration is great, then the line slopes up steeply (i.e., the slope is great).
