Answer:
(B) Energy transfer between trophic levels is almost always less than 20% efficient.
Explanation:
The ultimate source of energy on the Earth is the Sun. The energy coming from the Sun is captured by green plants by the photosynthesis. During photosynthesis sun energy is fixed into chemical energy (carbohydrate). So, in an ecosystem energy flow is unidirectional (from sun to the green plants). The fixed chemical energy from green plants is transferred to the herbivores then to carnivores through food. When one organism eats another organisms, only 10 % of the energy present in the organism is transferred as a food for the next organism and a large amount of energy is lost as heat into the environment. Thus, energy keeps on decreasing when stored energy moves from producers to top consumers. Thus, less than 20% energy transfer limits the trophic levels in most of the ecosystem.
The correct option is this: THE MASS OF THE PROBE REMAINS THE SAME, BUT THE WEIGHT OF THE PROBE DECREASES.
The mass of an object is a measure of the amount of substance it contains and this amount always remain the same unless there is a change in quantity of matter. This is the reason why the mass of a substance will remain constant, no matter where it is placed, whether on planet earth or on another planet. The weight of a substance on the other hand is a force, whose value depends on the force of gravity. Thus, the force of gravity that exist in the place, where the object is placed will determine its weight.
The organs that are involved in the excretion of water from the body include:
1. Kidneys (Primary organ for water removal)
2. Skin
3. Lungs
The kidneys play a key role in maintaining the water balance of the body. The kidneys control the water levels in the body by conserve water when there is shortage, and they can expel excess water by diluting the urine.
The skin has water in it. This water gets lost to the atmosphere by the process of evaporation. This is independent of the process of sweating wherein the skin actively releases water in the form of sweat to cool the body.
Our breath has a lot of moisture in it. This moisture is present due to the evaporation process taking place within the lungs due to the heat of the body. Thus lungs also become a part of the water loss mechanism.
