The graph shows the population of alligators and insects in a pond ecosystem where cricket frogs live. how will this impact the population of cricket frogs over time? decreases because the number of predators increases increases because the number of predators increases decreases because the number of prey decreases increases because the number of prey decreases

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.

colors do exist. the color of the sky is actually violet; humans percieve the color of the sky as blue.
