Answer:
Around 100,000 years ago, the Earth was going through a period of Ice Age. While the Glacial Period was not in full effect, it is reasonably concluded by researching the ending of the Ice Age and other Glacial Periods that the Earth was considerably colder than it is right now.

Answer:
The teeth in the mouth bite off a piece of food.
The teeth continue to break the food into smaller pieces.
Saliva rushes into the mouth and mixes with the broken-down food.
The food travels down the esophagus.
The muscles of the stomach churn the food and continue to break it down.
The broken-down food, called chyme, enters the small intestine.
The remaining food passes into the large intestine. Water is absorbed from the large intestine and the rest of
the material is stored as solid waste until it is excreted from the body.

Explanation:
The Gross Annual Primary Productivity for the wetland ecosystem is the amount of carbon taken up by the aquatic producers through photosynthesis.
Given that: Net Annual Primary Producer is 8,000 kcal/m2 per year, and respiration by the aquatic producers is 12,000 kcal/m2 per year, using the formula NPP = GPP – Respiration, we can determine the Gross Annual Primary Productivity of the wetland ecosystem.
NNP = 8,000 kcal/m2
Respiration = 12,000 kcal/m2
GPP = x
8,000 = x – 12,000 (NPP = GPP – Respiration)
Solve for x:
x = 8,000 + 12,000
x = 20,000 kcal/m2 per year
GPP = 20,000 kcal/m2 per year
