A herd of cattle has recently been moved to a large pasture containing native ryegrass and a weed called leafy spurge
The landowner wants
to improve the pasture for cattle grazing. She does some research and finds these facts:

Leary spurge is a competitive invasive plant; it produces a compound that actively prevents the growth of other plants nearby

• Cattle do nor choose to eat leafy spurge.

Sheep can be trained to eat leafy spurge and goats will seek it out

Ryegrass reproduces and spreads quickly after close grazing.

• Ryegrass is a popular food choice for both cattle and sheep.

Based on these facts, predict what will most likely happen to the reproductive success of ryegrass in the pasture over time.
