How does mushroom coral work with microplastics

Mushroom corals also ingest plastic particles, with a higher probability of retaining biofouled plastics, possibly because plastic that has been in the marine environment long enough to be colonized by micro- and macro-organisms becomes more palatable to corals.

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.

multiply it by 5 in order for you to understand i cant give an exact answer.
