Why is water considered a potentially limited resource at the watering hole?

• It is overly abundant

• Animals do not need much water

• The watering hole is very deep

• There is not much water available

What condition of the grasses suggests that food might be a limiting resource?

• Many grasses are dead or dried out

• There is an abundance of grass

How could more water availability influence the grass population?

• Enable more grasses to grow

• Increase competition among grasses

• No effect on grasses

• Decrease grass growth

What would likely happen if space became a limiting resource?

• Competition for space would intensify

• Animal populations would increase

• More water would become available

• Animal populations would decrease

• It increases population growth

• It limits population growth

• It only affects plant populations
