Ahealthy, balanced ecosystem has a. fewer producers than consumers b. more quaternary consumers than primary consumers c. more producers than consumers d. fewer primary consumers than tertiary consumers

the healthy, balanced ecosystem always has more number of producers than the consumers. every food chain starts with the producers. the producers are the ones that convert the energy from the sun in the form of glucose in the cells. these are consumed by the primary consumers, and subsequently by the secondary and tertiary consumers. thus, it is important that the number of producers should be more so that the consumers can feed on them properly and the food chain is not compromised. hence, the answer is 'option c - more producers than consumers'.

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
