Answer:
A. Chemical energy is used by each of the organisms in the food pyramid, resulting in less energy as it moves up the pyramid.
Explanation:
Green plants are autotrophs. They manufacture their own food through photosynthesis. Through sunlight, the food manufactured has chemical energy stored in them which is made available to the heterotrophs. Heterotrophs are mainly consumers, while autotrophs are producers.
Heterotrophs rely on autotrophs for their nutrition.
Thus, as consumers above at the top of the pyramid feeds on those below, the stored energy is being transferred up and used. These energy reduces as it goes up right to the top of the pyramid.
The best statement that describes how chemical energy is transferred up the pyramid is: "A. Chemical energy is used by each of the organisms in the food pyramid, resulting in less energy as it moves up the pyramid."
The aortic valve is in the left ventricle. When the heart muscle contracts (or beats), it is pumping blood out of the heart. ... The right side collects oxygen-poor blood from the body then pumps it to the lungs where it can pick up oxygen and release carbon dioxide.
Limitation in independent movement of extremities can be a problem not just to the patient but also of the health care team. The goal is to assist patient for exercise,have a safe environment,demonstrate the use of mobility devices like walker and crutches.To complete the objectives in achieving the goal the nurse should first assist patient in performing the passive and active ROM exercises,assist patient in using crutches or walkers and provide safe environment through increasing side rails in the bed. To know if the interventions work the patient should show she is still doing the activities of daily living inspite of her condition.
