Armed with their findings, the team presented their research to the villagers and the local agricultural authorities. Together, they worked out a plan to reduce the use of pesticides in the agricultural fields and to implement more sustainable farming practices.

What are the raw materials for photosynthesis? ().

This unit explores the fundamental relationship between living organisms and the atmosphere.

Their first task was to collect data on the butterfly population. They set up traps and observation decks to monitor the butterflies' behavior, feeding patterns, and habitats. After weeks of collecting data, they noticed that the butterflies were mainly congregating around a specific area of the forest, which was dominated by a particular type of flower.

The team hypothesized that the pesticides were disrupting the butterflies' life cycle, leading to a decline in their population. To test their hypothesis, they designed an experiment to compare the effects of pesticides on butterfly populations in different areas.

Leading the research team was Dr. Emma, a renowned entomologist who had spent years studying the behavior and habitats of butterflies. She and her team, including her assistants, Alex and Maya, set up a research station near the forest to begin their investigation.

: Light energy and chlorophyll (found in chloroplasts).
