Could someone answer these questions? I am having trouble. Thanks

i) Outline the benefits to an organism in raising its body temperature above that of its environment.

ii) What kinds of organisms are able to do this?

Hmmm, but a lot of body temperatures of marine animals are already above its environment - the sea. e.g whales and dolphines, seals etc.

Even human's body temp. of 37 degress Celsius is above the ambient temperature of around 25.

I can't see the point of this question.

I don't think it means an action of raising it above its normal temperature, just if its normal temperature is above the ambient

in which case:
i) the higher temperature may provide optimum conditions for enyme activity

ii) mammals and birds, they are endothermic, eg, humans, or as Survivor39 said, marine mammals such as dolphins, whales, seals etc..., (where as reptiles, amphibians, insects and fish are all ectothermic)

ok, have fun, tata
