Answer:
Hiya!!
Many factors, both natural and human, can cause changes in Earth's energy balance, including: Variations in the sun's energy reaching Earth. Changes in the reflectivity of Earth's atmosphere and surface. Changes in the greenhouse effect, which affects the amount of heat retained by Earth's atmosphere.
Answer:
The reactants for photosynthesis are light energy, water, carbon dioxide and chlorophyll, while the products are glucose (sugar), oxygen and water.
During chemosynthesis, bacteria living on the sea floor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide (dissolved in sea water). Pure sulfur and sulfur compounds are produced as by-products.
