What is the energy change taking place when plants make food in the presence\ of sunlight? potential energy is transformed into kinetic energy. kinetic energy is transformed into potential energy. chemical energy is transformed into radiant energy. radiant energy is transformed into chemical energy.

Option D,  Radiant energy is transformed into chemical energy.

Explanation:

All plants and trees consists of chlorophyll which capture energy from sun and convert it into glucose.

The energy obtained from sun is used by plants/trees in chemical reaction  involving carbon dioxide and water to produce glucose and oxygen.

This energy obtained from sun is known as radiation energy and the energy contained within glucose is called chemical energy.

Thus, when a plant makes food in  presence of sunlight , radiant energy is transformed into chemical energy

Option D is correct

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.

explanation:

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.
