Explain how competition in or among species can be both positive and negative.
Competition can keep species from growing past the capacity but it can also cause limited resources
Explain short-term environmental change.
Short Term- 0-5 years and does not allow organisms time to adapt
Explain long-term environmental change.
Long Term- 5+ year and allow organisms time to adapt
Short-term environmental change.
hurricane
Long-term environmental change.
Volcano
Positive Human Impact on the ocean systems.
Artificial Reefs- positive because it provides housing for fish and feeding grounds for larger fish
Negative Human Impact on the ocean systems.
Sound Impact- negative because it can alter the behavior of marine animals and prevent them from hearing important sounds
Negative Human Impact on the ocean systems.
Marine Debris- negative because it poses a threat to marine ecosystems
Negative Human Impact on the ocean systems.
Overfishing- negative because fish populations cannot be renewed quickly enough
Negative Human Impact on the ocean systems.
Oil Spills- negative because it kills wildlife and contaminates water and soil
Negative Human Impact on the ocean systems.
Runoff Pollution- negative because it pollutes rivers and oceans
Short-term environmental change.
oil spill
Long-term environmental change.
Global Warming
