Definition of heterotroph in English: heterotrophnoun ˈhɛt(ə)rə(ʊ)trəʊfhɛt(ə)rə(ʊ)ˈtrɒfˈhɛdərəˌtrɑf Biology An organism deriving its nutritional requirements from complex organic substances. 〔生〕异养生物。比较AUTOTROPH Compare with autotroph Example sentencesExamples - Classified by the source of their energy, bacteria fall into two categories: heterotrophs and autotrophs.
- Unlike plants, animals are heterotrophs which means they are unable to live on inorganic nutrients alone.
- Animals, on the other hand, are heterotrophs, life forms that depend on the consumption of plants, animals or both in order to meet their bioenergetic requirements.
- This photosynthetic control of cell-cycle progression is similar to the nutritional control of heterotrophs.
- The result, especially when heterotrophs are preyed upon by other heterotrophs, is a food chain.
Derivativesadjective Biology They commonly occur as free-living, photosynthetic and marine unicells and also include endosymbiotic, parasitic, heterotrophic and freshwater taxa. Example sentencesExamples - Overall, the results stress the importance of both heterotrophic and phototrophic metabolisms when considering environmental controls on the structure of bacterial communities in the sea.
- Physiologically, plant conversion or seedling development involves a transition from the heterotrophic embryo to an autotrophic plant.
- One of the most dramatic effects of light on plant development is observed in the de-etiolation process of photomorphogenesis, when plants pass from heterotrophic to autotrophic life.
- In this case, changes in photosynthetic activity enable comparisons to be made between mitochondria in autotrophic and heterotrophic tissue.
noun Biology Based on polyp size, corallite structure, and surface area considerations, M. faveolata appears to depend on photoautotrophy versus heterotrophy to a greater extent than its congener, M. cavernosa. Example sentencesExamples - Results suggest that the excess organic matter from these tropical estuaries supports heterotrophy in the adjacent coastal ecosystem
- This dynamic nature of the evolutionary changes must have been responsible for the breakdowns of the pathways, resulting in profound differentiation of heterotrophy among the species.
- After greening and probable transition from heterotrophy to autotrophy, root growth rate was enhanced and growth followed a linear pattern.
- If detached leaves were fed glucose, inducing a rapid switch from autotrophy to heterotrophy, then they were seen to exhibit GPT activity.
