Answer;
-Cougar
Explanation;
-The amount of biomass decreases from the lowest trophic level to the highest. In all the ecological pyramids, producers (organisms that produce their own food) are found at the lowest trophic level. This trophic level contains the highest amount of energy.
-The organisms in the highest trophic level receives the lowest amount of energy. This is because only 10% of energy moves from one level of the food pyramid to the next. When heat comes from the sun. 90% of it is lost to the environment, 10% is consumed by the plants (primary producer). As a primary consumer ingests the plant, 90% of the original heat from the sun is lost to the environment and the primary consumer receives 10%. The secondary consumer receives 10% and 90% is lost, and so forth.
The right answer is C) convection.
Convection (thermal) refers to the transfer of thermal energy within a moving fluid or between a moving fluid and a solid wall. This transfer of energy is achieved by two modes of "elementary transfer" combined that are advection and diffusion.
Convection (thermal) constitutes, with (thermal) conduction and (thermal) radiation, one of the three modes of heat exchange between two systems, and differs from them by the transfer method.
Thermal convection occurs when the body is in direct contact with the fluid.
