Answer:
A. decomposers transfer nutrients back to the soil
As we know that;
Density= mass/volume
By rearranging
Mass=. Density* volume
Mass=. 0.2*45
Mass=. 9 grams

I will answer the question accordingly so that it help you under stand it better.
Question A.
During an extreme heat wave, plants with white flowers survive better.
What mechanism is in work here?
Answer: Mechanism of Natural Selection
will work here. This is called survival of the fittest which means the best color which fits in harsh conditions will dominate over others and will survive for longer time.
What is the effect on the gene pool?
Answer: The Frequency of white allele will increases
because white color is the best fit to extreme heat wave.
Question B.
A person uproots the five closest plants, which all happen to have white flowers.
What mechanism is in work here?
Answer: The mechanism of gene flow will work here as color of flower represents genotype of flower.
What is the effect on the gene pool?
Answer: The Frequency of white allele will increases because genotype of white flowers is increased.
Kinetic energy plus the sum of two types of potential energy make up mechanical energy. Kinetic energy is the energy of motion.
