Define the following terms:
(a) Symbiotic relationship
b) Nutrients (c) Saprotrophic mode of nutrition d) Photosynthesis
Answers
Answer:
(a)Symbiosis is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic. The organisms, each termed a symbiont, may be of the same or of different species.
(b)substance that is needed to keep a living thing alive and to help it grow
(c)Saprotrophic nutrition is a mode of nutrition in which the organisms feed upon dead and decaying plants and animals. Organisms which follow this mode of nutrition are known as saprotrophs. For example: Mushrooms.
(d)the process by which green plants turn carbon dioxide and water into food using energy from sunlight
Answer:
( A) Symbiotic
A symbiosis is an evolved interaction or close living relationship between organisms from different species, usually with benefits to one or both of the individuals involved. ... Endosymbiosis is a symbiotic relationship, occurring when one of the symbiotic partners lives within the body of the other.
( B) Nutrients
A nutrient is a substance used by an organism to survive, grow, and reproduce. ... Essential nutrients for animals are the energy sources, some of the amino acids that are combined to create proteins, a subset of fatty acids, vitamins and certain minerals.
(C) Saprotrophic
Saprotrophic nutrition /sæprəˈtrɒfɪk, -proʊ-/ or lysotrophic nutrition is a process of chemoheterotrophic extracellular digestion involved in the processing of decayed (dead or waste) organic matter. It occurs in saprotrophs, and is most often associated with fungi (for example Mucor) and soil bacteria.
(D) photosynthesis
Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
