Question

Consider the example of the New England Grassland ecosystem. Identify the false statement.

Select one:

a.

plant productivity decreased but plant species evenness (number of species) increased when grasshoppers (herbivores) and wood spiders (carnivores) were both present

b.

loss of wolf spiders allowed for the grasshopper population to increase

c.

loss of grasshoppers allowed for plant productivity to increase but plant species evenness to decrease

d.

all individual plant species increased their numbers by having herbivores and carnivores present

Answer 1

d.

all individual plant species increased their numbers by having herbivores and carnivores present

if both are present then  the grasshopper experiences a fear trigger, though -- like in the presence of a wood spiders and he consumes more plants.
