Answer all question
4-CARBON CYCLE-the series of processes by which carbon compounds are interconverted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.
NITROGEN CYCLE-the series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.
OXYGEN CYCLE-The Oxygen cycle is the biogeochemical cycle that describes the movement of oxygen within and between its three main reservoirs: the atmosphere , the total content of biological matter within the biosphere, and the lithosphere
3(a)-Energy flow through an ecosystem is one way, because when the energy enters the plants (from the sun) during photosynthesis.This energy is then passed on fromone organism to another in a food chain but it does not come back.
(c)- A pyramid of energy depicts the energy flowform one trophic level to another trophic level in the food chain.
(b)-The most important biogeochemical cycles are the carbon cycle, nitrogen cycle, oxygen cycle, phosphorus cycle, and the water cycle. The biogeochemical cyclesalways have a state of equilibrium. The state of equilibrium occurs when there is abalance in the cycling of the elements between compartments.
