Question

8 multiple choice 1 point in some areas, cattle on an open range may compact fragile soils while grazing. this can damage plant roots, leading to fewer, smaller plants, which may in turn cause cattle to graze more and work harder to obtain food. this is an example of a homeostatic system negative feedback loop food web positive feedback loop dynamic equilibrium clear my selection

Explanation:

1. Analyze each option:

• Homeostatic system: Maintains internal stability, not matching the escalating grazing - plant damage cycle.
• Negative feedback loop: Counteracts changes to restore balance, but here the cycle amplifies (cattle grazing damages plants, leading to more grazing).
• Food web: Shows feeding relationships between multiple organisms, not about a self - amplifying cycle.
• Positive feedback loop: A change is amplified, as cattle grazing damages plants, leading to more grazing (since plants are fewer, cattle graze more), which further damages plants.
• Dynamic equilibrium: A balanced state with small changes, not an amplifying cycle.

1. Conclusion: The scenario describes a positive feedback loop as the initial action (cattle grazing compacting soil and damaging plants) leads to a consequence (fewer, smaller plants) that further promotes the initial action (cattle grazing more).

Answer:

D. positive feedback loop
