The bog freshwater ecosystem is least productive because of the stability or we can say stagnant type. This type of ecosystem comprise of the evergreen shrubs, and trees and also a floor which will be covered with a thick carpet of the sphagnum moss. The animals like carnivore species will be found.

The depth of this type of freshwater is about 6-10 feet it can extend up to 16 feet.
Answer:
True
Explanation:
The linkage relation of two genes can be determined on the basis of calculating recombination frequency.
If the recombination frequency value is greater than 50% then the genes are not linked and if the value is less than 50% then the genes are linked.
In the given question, the crossover gametes formed will be Ab = 100
and aB= 106.
Therefore,
Since the recombinant frequency value is larger than 50% therefore the genes do not show linkage.
Thus, True is the correct answer.
