ECO Lesson 1-3 Test

You are monitoring a population of rabbits in a grassland ecosystem. A new predator, such as a fox, has moved into the area, increasing the predation pressure on the rabbits. You observe that the rabbit population has started to decline as a result. 1) What effect might the introduction of the fox have on the grassland ecosystem as a whole? 2) How might the rabbits adapt to the presence of the new predator over time? 3) What conservation measures could be taken to support the rabbit population in the face of increased predation pressure?

Choose one of the answers below and use examples to support your answer. 1) Habitats provide living organisms with food, shelter, water, and a place to reproduce. 2) Habitats provide only water and sunlight to living organisms. 3) Habitats are not important for the survival of living organisms.
