Preparing to Submit Online
The questions that the students will encounter online are listed below. They may prepare their responses in advance, before going online to submit. Note that lengthy responses are not required. The best responses will include evidence for the ideas presented.
Question #1 Adaptations
Science Olympiad students examined more than 225 owl pellets for this activity. The most common prey species found in the pellets were meadow voles. Meadow voles are often active at night. Describe two important adaptations that owls have to make them effective predators at night.
Question #2 Changing Land Use
Many of the prey species found in the owl pellets are commonly found in fields and agricultural land. How would the conversion of natural fields or agricultural land to urban and suburban land use affect an owl population?
Question #3 Impact
After examining more than 200 owl pellets, the data you submitted indicates that the average number of prey found in the pellets is 2.90. That is, almost three prey in each pellet. What impact does this have in the ecosystem where the owl lives?
