(H) Ch. 3 & 4 Review

The greenhouse effect is:

• an unnatural phenomenon that causes heat energy to be radiated back into the atmosphere.

• the result of the differences in the angle of the sun's rays.

• a natural occurance that maintains the Earth's temperature range.

• the result of an excess of nitrogen gas in the atmosphere.

A nutrient that is scarce or cycles slowly through an ecosystem

• Primary Productivity

• Greenhouse Effect

• Limiting Nutrient

• Carrying Capacity

Human activities such as deforestation or clearing a field or natural events such as a wildfire or flood are examples of:

• competitive exclusion principle

• symbiosis

• secondary succession

• disturbance

Series of changes that restore an ecosystem back to its original state after a disturbance:

• Primary Succession

• Secondary Succession

• Physical Changes

• Nutrient Cycles

How can human activity disrupt the carbon cycle? (Select ALL that apply)

• removing trees that reduce the amount of respiration being done and therefore reducing the amount of carbon dioxide (CO₂) into the atmosphere

• by burning fossil fuels, the stored carbon in the fuel becomes carbon dioxide and adding more greenhouse gases into the atmosphere.

• adding to the amount of fossil fuel being stored as carbon sink deep in the Earth, reducing the rate of climate change.

• removing trees that reduce the amount of photosynthesis being done and therefore adding carbon dioxide (CO₂) into the atmosphere

How do detritivores contribute to ecosystems? (Select ALL that apply)

• Recycling nutrients in an ecosystem

• Consuming producers

• Decomposing dead biological matter

• Being consumed by tertiary consumers
