میتونی لایو بذاری!

If a farmer introduced a new insect species that consumed both locusts and plants in an ecosystem, how would this most likely affect the existing food web?

1 ) 

The new species would become a new producer, increasing energy availability

2 ) 

The new species would create a new trophic level, simplifying the food web

3 ) 

The new species would act as both a primary and secondary consumer, altering feeding relation ships

4 ) 

The new species would have no significant impact as ecosystems are resistant to change
