Question

1. Describe in detail how osmoconformers are able to match the osmolarity of their environments yet maintain internal osmolarities ~300 mOsm.

2. Define Stenohaline and Euryhaline animals. What environments favor each of these responses (i.e. in what environments do you find euryhaline species, and what environmental conditions do we find stenohaline animals?)

Answer 1

The osmotic concentration of the body Fluid with that of ambient water Osmotic concentration, such animal and Plants are simply called Conformers Cosmocom farmers.) - Organisms should try to maintain internal Constancy of body is called. homeostasis For example :- Small animal have laugen Surface area according to their volume very fastly they loss. body heat in low Temperature due to this expand energy to generate body heat through metabolism. → you also know Human body maintain Constant Temperature of 37°C In summer it outside to The temperture higher than body Temperature then body start to Sweat this result in evaporation Cooling our body and brought down body temperature Normal and in winter body start to Shiverting and this exercise produce heat and raise body Temperature by all examples explantion and the process of homeostasis Osmo conformer maintain internal Osmolarities ~ 300 mosm.

2. Steno haline - organisms that tolerate only harrow range of salinities. Ewry haline - Organisms that tolerate to wide range of salinities. In aquatic habitat The quality of water is important like pH value, Salinity, water Temperature. - Stenohaline animal live in narrow range of salinities. ez steno y narrow haline & salt. ex:- goldfish s Eury haline animal live in that area in which have to tolerate. wide range of Temperature. Eury - wide. haline Salt. ex - Bullshark
