Explanation:
Siberian traps refers to the moment when the volcanoes of Siberia expelled a large amount of CO2 and HCl gases that are highly toxic and that promoted a mass extinction, that is, it caused the death of several living beings in a short period of time. This happened over 250 years ago and was caused by the steps:
It all started when volcanoes expelled large amounts of carbon dioxide into the atmosphere, which contaminated the atmosphere and caused a rise in temperature, creating strong global warming. This caused a great warming of the surface of the seas, which caused them to evaporate in great intensity and lose large amounts of oxygen and become anaerobic environments, conducive to the growth of bacteria producing hydrogen sulfide, which is a very toxic gas. This gas was released into the atmosphere, killing several living beings intoxicated with the contaminated air.
The correct answer is A. Tierra Fria.
Tierra Fria is composed of highlands, but even though it is very high area, because of the low latitude and high altitude, this area has a very pleasant climate which is actually pretty similar to the oceanic coastal regions of the temperate climates. Because of this, it is very suitable for the livestock, since the weather conditions are very nice, the grass is green for most of the year and it is in abundance, plus the region is clean, and also lacks predators.
Answer:
9.) <em>Humpback Whales</em>
10.) <em>Phytoplankton.</em>
11.) <em>Sotronger upwelling winds</em>
Explanation:
9.) A primary consumer feeds on primary producers, of all the options given Humpback Whales, are the only ones meeting the criteria in the options given since they feed with plankton (a primary producer).
10.) Phytoplankton are the base of the Southern Antarctic Ocean trophic chain. In the nutrient-rich upwelling zone waters, they can reach huge blossoms and are far more common than other forms of zooplankton in this zone.
11.) The productivity of this ecosystem is influenced by the seasonal cycle of the upwelling winds, these peak during the months of December and January, carrying more nutrients and allowing trophic networks to work more efficiently and actively allowing for more productivity.
