Algae exist in environments ranging from oceans, rivers, and lakes to ponds, brackish waters, and even snow. 3. For instance, algae living in snow contain carotenoid pigments in addition to chlorophyll, hence giving the surrounding snow a distinctive red hue. modifications to the Pascher and smith classification Fritsch classification In animals these substrates are taken through ingestion and assimilated through digestion while in Plants these substrates( glucose a carbohydrate) are formed through Photosynthesis.
