Photosynthetic pigments: They possesses chlorophyll a, chlorophyll b and small amount of β-carotenoids. Heterotrophic Nutrition – Types Of Heterotrophic Nutrition With Examples Types Of Heterotrophic Nutrition Heterotrophic Nutrition: It is a mode of nutrition in which the organisms obtain readymade organic food from outside sources. Mode # 3. There are certain organisms that lives together and provides food and shelter to each other. Pinocytosis. Symbiosis is mutually beneficial association existing between two organisms and both organisms derive benefit from each other without causing any harm to each other. In the autotrophic mode, organisms use simple inorganic matters like water and carbon dioxide in the presence of light and chlorophyll to synthesize food on their own. There is substantial evidence for the health benefits of algal-derived food products, but there remain considerable challenges in quantifying these benefits, as well as possible adverse effects. photosynthesis to obtain a part of the food required by them.

Ans. Both are found in fresh and salt water environments. Golden-brown algae and diatoms are the most abundant types of unicellular algae, accounting for around 100,000 different species. The Then they absorb the nutrients from it. Therefore bacteria known as Rhizobium present in the roots of gram, peas, moongbeansand other legumes converts the atmospheric nitrogen into soluble form that dissolves in soil and can be easily absorbed by plants. From where do the plants obtain nitrogen? Question 3. Solution: (c) Bread mould, yeast and mushroom are all fungi that derive their food from non¬living organic matter. needed for their growth. organisms live together and share shelter and nutrients. The process is called photosynthesis. There are three sensitive hairs in the center of each half of each leaf. It is the largest class of algae; They are commonly known as green Algae. and minerals are transported to the leaves by the vessels which run like pipes dioxide from air is taken in through stomata present on the surface of the energy of the sunlight. Algae, identified as a heterogeneous group of microorganisms, range from the microscopic blue-green algae (gram-negative bacteria) to large, complex seaweeds, measuring up to a few meters. Good nutrition means your body gets all the nutrients, vitamins, and minerals it needs to work its best. So it lives in the roots of Spirogyra, any member of a genus of some 400 species of free-floating green algae found in freshwater environments around the world. These soluble Some plants are dependent on other plants and animal for their food. You can understand this better in animals and human beings as you see it on a daily basis. (c) Mode of nutrition is either autotrophic or heterotrophic.
