第一小问【对当前⽣态系统进⾏建模】

Model the current ecosystem. Build a basic food web model for this new
agricultural ecosystem which recently took the place of a heavily forested region.
Include the producers and the consumers as well as the impact of the agriculture cycle
and its seasonality which changes the system dynamics over time. Consider the impact
of herbicides and pesticides by including the effects of chemical use on plant health,
insect populations, bat and bird populations as well as the ecosystem stability.
