Question

Imagine that a new grazing herbivore expands its range into the area where these plants live. It

preferentially feeds on the tallest plants, while the smaller herbivores already present feed on the

shortest plants. Which phenotype will be selected for?

Answer 1

Smaller herbivores completely feeds on smaller plant because they are not able to reached at taller plants so competition among the small herbivores increases because small plants and limited and population of smaller herbivores is large but new grazing herbivore expand it's range to taller plants due to better adaptation to changing environment and change their genetic makeup so they can survive easily i, e survival of the fittest

So taller pant will phenotypically selected
