The bottom of the pyramids are the producers and primary consumers and the top are the secondary and tertiary consumers. The bottom is bigger because it gives all the primary consumers 10% of their energy, the primary consumers give off 10% of their energy to the secondary and so on. The bottom represents how much energy is started off with and by the time you get to the tertiary consumers there is little energy left and that’s why the top is smaller.
Answer: A) affects genotypic expression of characters.
Explanation:
Environmental variations cause several affects on the genotypic expression of characters. Genotype is defined as the genetic that prepare in the individual so that it has production of protein which after that involving with the environmental components result in the physical characteristic named as phenotype. Therefore, environmental variation cause more affect on the genotypic expression more than itself.
They cool off the water or warm it up
When it comes to freshwater wetlands, hydrology plays a large role in
nutrient stoichiometry and sensitivity to nutrient inputs. Although
wetland biogeochemists intuitively understand these important
relationships between landscape position, hydrology, and sensitivity to
nutrient inputs, these relationships have never been quantified using
geospatial data. The objective of this project will be to evaluate and
quantify the linkages between watershed catchment characteristics and
freshwater wetland nutrient sensitivity ur welcome
