Answer:
Explanation:
Minnesota's hardwood forests developed in the absence of earthworms. Without worms, fallen leaves decompose slowly, creating a spongy layer of organic "duff." This duff layer is the natural growing environment for native woodland wildflowers.
Answer:
The growth rate is 1250 per year.
Explanation:
- First of all, lets consider the population number in both years;
The initial population is 1200, and
Final population is 3700.
- Total increased population is (3700- 1200) = 2500
So 2500 population were increased in (2006 - 2004)= 2 years.
- To find the annual growth rate: (Increased population/ time span in years)= 2500/2= 1250 per year.
- Hence 1250 population was added per year in walleye from 2004 to 2006.
Answer:
Thermosphere.
Explanation:
The thermosphere and the exosphere together form the upper atmosphere. ... Because there are relatively few molecules and atoms in the thermosphere, even absorbing small amounts of solar energy can significantly increase the air temperature, making the thermosphere the hottest layer in the atmosphere.
