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.
The answer is B. I believe that this is the answer because the barnacle is benefiting from the gray whale without harming, or affecting it in the process.
Revolution means going around some point: Earth moves around its axis once per day and around the Sun once per year.
I am assuming here that you mean the revolution around the sun (around its own axis would be 360 degrees a day, a full circle, but the phrase is more commonly used to describe movement around the sun).
it revolves a full circle each year, that is 364 days. So each day it makes 360/364 Degress, that is approximately one degree per day - the answer is 1)
Answer:
estimated CEC for given hypothetical soil is 26.25 meq/100g.
Explanation:
Average CEC in smectite = 62.5 meq/100g. Since it ranges from(25-100 meq/100g)
Average CEC in kaolinite = 10 meq/100g.
Average CEC in organic matter = 325meq/100g.
Range(250-400 meq/100g).
Estimated CEC for given soil will be,
= 26.25 meq/100g.
Answer:
Some ways to help fight climate change are :

- use less AC / heating
- take shorter showers ( to use less hot water)
