If the diploid number in a liver cell is 52, how many chromosomes are there is the egg of this organism?

Gametes or sex cells (sperm and eggs) contain half the number of chromosomes that exist in autosomal cells; they are haploid. Therefore in the case where the diploid number of chromosomes is 52, the haploid number would be half of that, meaning 52/2 = 26.

An immediate effect of the construction of roads and parking lots on the transfer of energy from producers to consumers in an ecosystem would be a decrease in the number of producers. This is because the producers need to live in the soil/land that was once not developed.
