Discourage the dog from barking during the day and night by always ignoring barks; reward the dog with play and attention when the dog is not barking, and ignore the dog when it is barking. Positive reinforcement will help the dog to learn that barking, during the day or night, does not result in a reward.
The green pigment chlorophyll chlorophyll, green pigment that gives most plants their color and enables them to carry on the process of photosynthesis. Chemically, chlorophyll has several similar forms, each containing a complex ring structure and a long hydrocarbon tail......
Other Pigments. There are other pigments found in algae that are similar to chlorophyll, though they do not directly capture sunlight. One example is carotenoid, which is a brown pigment (and is found in brown algae which, similar to dinoflagellates, can cause an algal bloom).dditionally, some types of algae have chlorophyllin and phycobilins, which are water-soluble salt derived from chlorophyll used to help capture sunlight (though photosynthesis does not occur in either one), and which are also found in the chloroplast.
