What would be an immediate effect of the construction of roads and parking lots on the transfer of energy from producers to consumers in an ecosystem? a. a decrease in the number of producers. b. a decrease in the number of consumers. c. an increase in the number of producers d. an increase in the number of consumers.

The correct answer would be A. a decrease in the number of producers.

Human activities like construction of roads, parking lots, buildings et cetera lead to the deforestation due to which producers like grass, plants, trees, et cetera are removed from the area.

Thus, the number of producers is adversely reduced.

Consequently, less amount of mass and energy are available at a primary trophic level.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
