Answer:
The correct answer is - decreased population size at all levels.
Explanation:
A decrease in the productivity of producers of an ecosystem will lead to a decrease in all other organisms of the ecosystem including top-level consumers to the bottom-level producers due to the fact that producers provide energy and food to primary consumers.
It is because they are the only organisms that convert the sunlight to usable energy and food that transfer from one trophic level to other, so if the population of producers or their productivity will decrease then there will be decreased population size at all levels.

Answer:
DNA double strands are run in opposite direction
Explanation:
The DNA is a macromolecule and is made of the polynucleotide. In a DNA, Polynucleotides are arranged in two strands or helices. The two strands are joined together by hydrogen bonds. Each stand has two ends. One end is called 5’ (5 prime) and the end is known as 3' (3 prime). The two stands in a DNA run in antiparallel or in an opposite direction. It means at one end, one strand is 3' and the other is 5' and at the other end one strand is 5' and another strand is 3'.
