Explanation:
Energy pyramid: is a model that shows the flow of energy from one feeding level to the next in an ecosystem. It compares the energy used by organisms at each trophic level.
Unit: kilocalories (kcal).
While Biomass pyramid is a statistical graph that shows the biomass present in a unit area of various trophic levels. It shows the relationship between biomass and trophic level. It quantifies the amount of biomass available in each trophic level of an energy community at a given time.
Unit: grams per square meter (g/m^2), or calories per square meter (K/m^2).

Answer:
The value is 
Explanation:
From the question we are told that
The temperature is 
Generally the root mean square speed of the oxygen molecules is mathematically represented as
Here R is the gas constant with a value 
M is the molar mass of oxygen molecule with value 
So
=>
Answer:
D. Solution
Explanation:
Sugar dissolved in water is an example of solution.
A solution is a homogenous mixture of solutes and solvents.
In a solution the solute particles ae distributed uniformly in the solvents. The solute is the substance and it is the sugar here that is dissolved to make a solution.
The solvent is the water in this instance that helps to dissolve the solute.
