In an aquatic ecosystem, the fishing of a particular fish species increased. this fish species is a secondary consumer in an energy pyramid. the fishing of the species led to a decrease in its population. in which two ways will this affect the food web? the higher levels in the pyramid will receive more energy. the higher levels in the pyramid will receive less energy. the lower levels in the pyramid will have less predation. the higher levels in the pyramid will receive no energy at all. the lower levels in the pyramid will receive less energy.

The higher levels in the pyramid will receive less energy.

As, it is stated that the fish species is secondary consumer in an energy pyramid. Secondary consumers are those organisms which depends upon primary consumers and primary producers for their food requirements, these can be Carnivores (meat eaters) or Omnivores (plant and meat eaters). Energy in a energy pyramid moves according to 10% law which says that energy at each subsequent higher level decreases by 10%, so the highest level in energy pyramid receives least energy. Fishing will led to decrease in population of fish species which is a secondary consumer, therefore energy received by higher level will be less.

The lower levels in the pyramid will have less predation.

The fish species being secondary consumer can be dependent upon primary producers like plants, phytoplanktons or other fish species for food requirements. As, this fish species depends upon other species for obtaining energy in the form of food, it's role is of predator in food web therefore, when this species decrease in population lower level species will get better chances of survival in absence of predation.
