Describe autotrophs, heterotrophs, saprotrophs, parasite and symbiosis with example
Answers
Answer:
Autotrophs are known as producers because they are able to make their own food from raw materials and energy. Examples include plants, algae, and some types of bacteria. Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs.
Saprotrophs take their food in solution form, from dead and decaying matter. Bacteria, fungi, and fungus-like organisms are examples of saprotrophs. Saprotrophic microbes fungi are also known as saprobes and saprotrophic plants are called saprophytes.
Parasitic nutrition is where an organism lives in or on its host and acquires nutrition at the expense of its host. Examples include lice and tapeworms.
Symbiotic nutrition is the relationship between organisms in which they share their nutrition and shelter. This mutual relationship may or maynot be beneficial to both the partners.Examples: Leguminous plants shows symbiotic nutrition mode. Alga and fungus live together. ... In return, alga provides food prepared by photosynthesis.
