What effect could an uncontrolled grass carp population have on the energy pyramids of a lake environment?

Grass carp can grow nearly 5 feet long, up to 80 pounds, and capable of eating nearly 150% of it's body weight   Grass carp could drain the vegetation in an aquatic environment. This would remove a large portion if not all of the producers from the aquatic environment. Death through starvation would occur all the way up the energy pyramid

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
