Study Notes
Nutrition in Organisms
- Ticks and leeches are classified as ectoparasites, organisms that derive nutrition from a host by feeding on its blood.
- Some organisms, like fungi and bacteria, are saprotrophs, which break down dead organic matter outside their bodies.
- The range of food material that an organism can consume and break down is determined by its digestive enzymes, which are specific to certain types of molecules.
- Differences in the access and consumption of food among organisms are facilitated by their nutritive apparatus, including mouthparts, digestive systems, and feeding mechanisms.
- Aphids, for instance, are examples of herbivores that derive nutrition from plants without killing them, a process known as phloem feeding where they obtain sugars and other nutrients directly from the plant sap.
