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.
Answer:
<u>14°C</u>
Explanation:
Place A = 2500 m = 20°C
Place B = 1500 m = ? °C
First of all, we know that <em>the air temperature decreases with 6°C at every 1000 m.</em>
So, now it is easy to find the temperature from place B.
If in place A, at 2500 m is 20°C, then at place B the temperature will be with 6°C lower.
Place B = 20°C - 6°C = <u>14°C</u>
Answer: <u>A metal </u>is rare on Earth but relatively abundant in iron-rich meteorites. It has been found in widespread layers on Earth and it's date of deposition coincides with the major extinction of life on Earth 65 million years ago, possibly indicating a connection between a large impact and this extinction.
Explanation: That metal would be iridium
