Question

select the correct answer from each drop - down menu. complete the paragraph by applying the laws of conservation of energy and matter to the interactions between earth’s subsystems. according to the law of conservation, both energy and matter are in natural systems. earth as a whole is a system, in which energy can move from one subsystem to another. as energy and matter are transferred between subsystems, different matter and energy interact. for example, during photosynthesis, carbon is transferred into the biosphere, while radiant energy from is being converted into chemical energy. during this process, the amount of carbon remains constant, but some of the radiant energy is transformed into energy.

Explanation:

1. The law of conservation states that energy and matter are conserved in natural systems, not created or destroyed.
2. Earth is a closed system regarding matter (but open to energy), where energy and matter can move between subsystems.
3. In photosynthesis, carbon is transferred to the biosphere and radiant energy from the Sun is converted into chemical energy. Some radiant energy is transformed into chemical energy while the amount of carbon remains constant.

Answer:

1. conserved
2. closed
3. the Sun
4. chemical
