Solution
The correct option is A Photosynthesizers, symbionts and mixotrophic
The major modes of nutrition are autotrophy (involving plastids, photosynthesis and the organisms manufacture of its own nutrients) and heterotrophy (the taking in of nutrients). Heterotrophy occurs as two types: phagotrophy, which is essentially the engulfment of particulate food and osmotrophy, the taking in of dissolved nutrients from the medium. Organisms that can utilize either or both autotrophy and heterotrophy are said to exhibit mixotrophy. Many dinoflagellates, for example, exhibit mixotrophy.
