Bio Ecological Niche Quiz

Autotrophic

using external energy sources to synthesize glucose from simple inorganic substances

Heterotrophic

using carbon compounds obtained from other organisms to synthesize required carbon compounds

Photoautotroph

organisms that uses light energy to generate ATP and to produce glucose from inorganic substances

Holozoic

nutrition in consumers where food is ingested, digest internally, absorbed and assimilated

Herbivore

animals that feeds exclusively on plants

carnivore

flesh-eating organism

niche

the role played by a species in its community including its abiotic requirements and tolerances, and its interactions with other organisms

Obligate aerobes

organisms that can only respire aerobically

Obligate anaerobes

organisms that only respire in the absence of oxygen

Facultative anaerobe

organisms that normally respires aerobically but has the facility to switch to anaerobic respiration in the absence of oxygen

mixotrophic nutrition

nutrition that is both autotrophic and heterotrophic

Saprotroph

organisms that lives on or in dead organic matter, secreting digestive enzymes into it and absorbing the products of digestion

Chemosynthesis

inorganic molecules are oxidized to release energy used to synthesize glucose

Chemoautotrophs

organisms that are chemosynthetic using energy from chemical reactions involving the oxidation of inorganic compounds to make glucose

Predation

biological interaction where one organism kills, predator, and eats another organism, prey

fundamental niche

the potential extent of a species based on adaptations and tolerance limits

realized niche

the actual extent of a species when in competition with other species

osmotrophy

uptake of dissolved organic material

Detritivores

organisms that ingest the dead organic molecules before digesting them into smaller and soluble ones
