The table below shows the habitat and foraging habits of two fish species in a marine ecosystem. Fish Species Data
Species Habitat Eating Habits
A Up to 1,000 meters deep Eats large fish
B Deeper than 1,000 meters Eats shrimps

An invasive species that lives in habitats up to 1,000 meters deep and feeds on small fish only was introduced in this ecosystem. What would be the likely impact?
Species A’s population will decrease due to limited space.
Species B’s population will decrease due to limited space.
The population of species A will decrease due to limited prey.
The population of species B will decrease due to limited prey.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.

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.
