deforestation

greenhouse gases

The large amount of energy from the sun is absorbed by the terrestrial land and water and some amount of energy is reflected back to the space this maintains the heat energy balance inside the planet earth. The atmospheric layers exhibit the large abundance of green house gases the process of deforestation (cutting and clearing of the forest cover on the land) also contributing potent greenhouse gas called as carbon dioxide. These gases exhibit a diatomic state which traps the energy from sunlight making the atmosphere warm and is responsible for global warming.

Hence, deforestation and greenhouse gases are responsible for deducting the energy from sun being reflected back to the space.

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
