The only source of energy in an ecosystem is the sun. The green plants make food by the help of photosynthesis. These plants are also eaten by the herbivores and then these herbivores animals are eaten by the carnivores animals present in the ecosystem.
The energy from the sun is transferred to herbivores, then from herbivores to carnivores.
Some amount of energy is also lost during the process of energy transfer.
The energy transferred from one level to another + the energy lost
The energy of the ecosystem can be best described as option C. The amount of energy entering an ecosystem from the Sun is equal to the amount used by organisms plus the amount lost as heat.
Surface currents in the Northern Hemisphere rotate in a Clockwise direction whereas in the Southern Hemisphere, the surface currents rotate in a anticlockwise direction. This happens because of the Coriolis effect, because of this Coriolis effect surface currents are shifted to angle of 45°. Therefore, it deflects the current towards right in northern hemisphere and towards left in southern hemisphere.
