Use the wоrd bаnk belоw tо fill in the blаnks of this description of the emergence of life into terrestriаl environments between the Silurian and end-Permian periods. WORD BANK: CO2, glaciations, amniotes, O2 , moist, greenhouse gases, arid, herbivorous tetrapods, mesophytic flora, water-based tetrapods As the Ordovician [___1___] receded, sea levels rose and the cooler, moister climate was fairly equable by the end of the Silurian. Complex terrestrial ecosystems began to flourish and stabilize rivers, providing fertile habitat for plants and animals along their banks. As plants diversified and dominated the landscape through the Devonian, they grew taller and provided [___2___] microclimates suitable for [___3___] to forage on land. [___4___] levels declined and [___5___] levels were the highest ever known on earth during the Carboniferous. The resulting cool, dry climate was beneficial to [___6___], which diversified and radiated with the ability to reproduce into drier highlands. This food source supported the first [___7___]. The increasingly [___8___] climates in the Permian also led to the success of [___9___] similarly no longer restricted to moist areas for reproduction. Herbivorous and predatory tetrapods in a range of sizes exist in complex temperate ecosystems. Massive amounts of [___10___] may have been released during volcanic eruptions over 10s of thousands of years, resulting in a runaway, cyclic greenhouse affect of global warming and ocean acidification, nearly ending all multicellular life on earth. This now cleared the stage for flora and fauna adept at dry-climate living to radiate.
