Question

If a limiting nutrient is supplied to the producer in the diagram above, what effect could it have on the birds?

Answer 1

Answer: The producers are the bluegrass. Adding a limiting nutrient to the grass would increase the amount of primary  productivity. The result would be an increased amount of biomass at the producer level, and increasing  biomass and available energy at each successive level. The number of birds could increase, because there  would be more for them to eat.

Hope this helped!!! :)

Goodluck!
