Question 4 (10 points) Human development that causes a formerly large habitat to be chopped into small
"Islands" of habitat is damaging to populations because
biodiversity is reduced
O small, isolate populations are more susceptible to disturbances
Othere is less space for individuals to breed, find food and water and find shelter
all of the above

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
