Name examples of:

a decomposer _______________

IF the population of grasshoppers were to die because of disease, HOW would that affect other organisms in that ecosystem? (the grass, birds, etc)

There would be more grass for other consumers to eat, there would be less birds because some of their food source is gone.... so the birds would either have to leave that ecosystem to find enough food elsewhere OR they would die because there isn't enough for them to eat

500

What would happen to the SOIL if there were no decomposers?

The soil would lack minerals and nutrients, thus no plants would grow, no plants, no herbivores, no herbivores, no carnivores, no LIFE

500

What would happen IF there were TOO MANY grasshoppers in an ecosystem?

The grasshoppers would eat all of the grass they could find. Then grass would be gone and they would struggle to find other sources of food. They would eat all of the insects. Meanwhile, other herbivores wouldn't have much grass to fight over for food, and birds would have plenty of grasshoppers to eat as well as other carnivores/omnivores, but the lack of insects AND grass would cause an imbalance within that ecosystem until many of the grasshoppers died.
