Answer AND Explanation:
A small portion of energy is passed from one trophic level to the next successive level. The rest is lost to the environment. The progressive loss of energy at each trophic level puts a natural limit on the total dry mass of living biomass that can exist at each successive trophic level. In a stable ecosystem, the biomass in any trophic level should be more than the successive level in order for it to support the successive level.
A plant absorbs energy from the Sun. Energy absorb by plants is used in the process called photosynthesis. As the plant takes the energy, it process it to turn it into potential energy. And is being used by the consumer of the plants. Hope this answers the question.
In adults, red blood cells are produced in the bone marrow, spend most of their lifespan in blood vessels and most are finally destroyed in the organ called the spleen.
Red blood cells or the erythrocytes are the cellular components of the blood involved in the transport of gases, nutrients and wastes. The process of production of red blood cells from the bone marrow is called the erythropoiesis. It is produced by the red bone marrow of the large bones. After maturity they remain circulating in the blood vessels like arteries, veins and capillaries transporting substances. Finally spleen is the organ involved in the destruction of the old or damaged red blood cells in the body.
