The answer is; in the summer
Insects such as blowflies increase their population in the summers when the temperatures are warm. One reason is that most insects are ectotherms hence their body temperatures are dependent on ambient environmental temperatures. In addition, the maggot stage of the blowfly pupates mostly in warm and dry conditions hence increasing winged flies populations in the summer.

Answer:
The energy flow in the ecosystem decreases as it flows from one trophic level to the next trophic level. Only 10% of the energy will transfer to the next trophic level and the remaining energy is lost in the other metabolic process.
The energy flow in the case of the grassland can be shown by the trophic relationship of the organisms. The sun is the primary source of the energy that are absorbed by the plants through the photosynthesis process. The cattle acts as herbivores will consume the plants energy by directly feeding on them. The ranch should be protected from the other animals that feeds on cattle and they are known as carnivorves.
