Studies indicate that for every square metre of area, a lake has 150 g of producers, 16 g of herbivores,
and 4.5 g of carnivores. This data may be used to draw a
(a) a pyramid of numbers
(b) an energy pyramid
(c) a pyramid biomass
(d) a pyramid showing the number of KJ for each trophic level

liquid crystals are matters in a state which have properties between those of conventional liquids and those of solid crystals[1]. liquid crystal is partially ordered and anisotropic. in terms of molecular order, liquid crystal molecules have one-dimensional or two-dimensional long - range order.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
