(a) Producers serve as a source of food in a grazing food chain and constitute the first trophic level and serve to incorporate nutrients into the body of living organisms whereas detritus food chain begins with detritivores that feed on the dead and decaying matter and serves to release the nutrients back into the atmosphere.
(b) Production refers to the rate of synthesis of organic matter by primary producers through the process of photosynthesis while decomposition refers to the breakdown of complex substances into simpler ones and is carried out by heterotrophic decomposers. 
(c) Number and biomass of producers are largest and gradually decreases while moving from primary consumers to top consumers; it gives upright pyramid while Inverted pyramids exhibit lowest quantity of selected attribute at producer level. 
(e) Litter constitutes both biodegradable and nonbiodegradable waste while detritus is the only biodegradable waste.
(f) Primary productivity refers to the total organic matter produced by primary producers per unit area per unit time while secondary productivity refers to rate conversion of food molecules into biomass at consumer level per unit area per unit time.

To comprehend plant-water relations an understand standard terms is necessary. Water potenterstanding of certain fundamental to understanding water potential is a concept and pressure potential are the two matent, Solute potential determine water potential. Water molecules possess kinetic energy. In liquid and gaseous form pure water aldreff. they are in random motion that is both rapid and constant. The greater the concentration of water in a system, the greater is its kinetic energy or water potential. If two systems containing water are in contact. random locer is solute potentid molecules from the system with higher energy to the one with lower energy. By a diding solute Thus water will move from the system containing water at higher water and Both of substances down a gradient of free energy is called diffusion. Water de creases. potential is denoted by the Greek symbol Psi or and is expressed in pressure units such as pascals (Pa). By convention, the water potential of pure water at standard temperatures, which is not under any pressure concentration = free eregy is taken to be zero. If some solute is dissolved in pure water, the solution has fewer free water molecules and the concentration (free energy) of water decreases. Root preva reducing its water potential. Hence. all solutions have a lower water potential transpisatfo than pure water, the magnitude of this lowering due to dissolution of a solute is called solute potential or ad atmp. the solute molecules, the lower (more negative) is the . For a solution at atmospheric pressure (water potential) (solute potential) /osmotic potential If a pressure greater than atmospheric pressure is applied to pure water or a solution, its water potential increases. It is equivalent to pumping water from one place to another. Can you think of any system in our body where pressure is built up? Pressure can build up in a plant system when water enters a plant cell due to diffusion causing a pressure built up against the cell wall. it makes the cell turgid (see section 11.2.2);
