An organism is discovered that thrives both in the presence and absence of oxygen in the air. Curiously, the consumption of suga
r increases as oxygen is removed from the organism's environment, even though the organism does not gain much weight. This organism:_______.a) must use a molecule other than oxygen to accept electrons from the electron transport chain b) is a normal eukaryotic organism. c) is photosynthetic. d) is an anaerobic organism. e) is a facultative anaerobe.
Anaerobes are organisms which can produce energy via the process of fermentation in the absence of oxygen. The anaerobes can be classified as facultative anaerobes and obligate anaerobes.
Facultative anaerobes are those which can carry out respiration in presence of oxygen but can choose to follow the fermentation pathway if oxygen is absent. Fermentation also uses glucose.
Aerobic respiration produces 32 molecules of ATP from one molecules of glucose while fermentation produces only 2 molecules of ATP . Thus when the organism switches to fermentation pathway it utilizes more and more glucose to reach its energy demands.
Considering all the above points we can conclude that observations indicate that the organism is a facultative anaerobe.
Flying foxes disperse the Cycad seeds if the seed sometimes get swallowed whole.
Explanation:
Cycads are gymnosperms they do not have seeds enclosed in fruit. Therefore the bats are not attracted to cycad fruit.
If the bats were susceptible to neurotoxin then they must not have been the frequent feeders of cycad seeds. Biomagnification of neurotoxin in flying fox is a widely researched topic.
Beetles do not have an association with these bats thus the bats must not be assisting them as important pollinating agents.
