Final answer:
Wet places with organic waste are prime spots for fly larvae. Such conditions plus producers' unused primary production being broken down by decomposers and mosquitoes as parasites form fundamental concepts in ecosystem dynamics.
Step-by-step explanation:
True. Wet areas where manure, mud, and plant debris accumulate indeed form ideal breeding habitats for fly larval development. These environments provide a rich source of nutrients for the larvae to feed on as they grow. Flies seek out such locations to lay their eggs, ensuring that their offspring have the necessary resources to develop. This principle ties into understanding how ecosystems function and the role of decomposers in breaking down organic matter.
Speaking of decomposers, most of the gross primary production that is not utilized by the producers themselves is indeed broken down by decomposers. This helps recycle nutrients back into the ecosystem, making them available for other organisms to use.
As for the nature of a mosquito feeding on human blood, it would be considered a parasite. This is because it lives on or in a host organism and causes harm while deriving its nutrients and energy. Unlike predators, parasites typically do not kill their hosts outright.
