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.
The precambrian era makes up about 90% of the earths history, but there was little to no living organisms at the time other than microscopic ones. The first eukaryotes were found in the cambrian period after the precambrian period, not only that but at the end of the precambrian era in the Proterozoic era there was a mass extinction of about 70-80% of all living organisms
The deep sea vent organisms or benthic organisms normally live in dark conditions because of no penetration of sunlight. These organisms in order to colonize ocean surface must develop photo sensory receptors and should adapt to the light conditions along with variation in temperatures and pressure in ocean currents.
