What is biological magnification?

Back

Biological magnification is the process by which the concentration of toxic substances increases in organisms at each successive level of the food chain.

What ecological problem is associated with the depletion of the ozone layer?

Back

The hole in the ozone layer is primarily caused by the release of chlorofluorocarbons (CFCs) and other ozone-depleting substances, leading to increased UV radiation reaching the Earth's surface.

Front

What event can trigger secondary succession?

Back

Secondary succession can be triggered by events such as forest fires, which clear an area but leave the soil intact, allowing for regrowth.

Front

What type of population growth is characterized by a stable population size?

Back

Stable growth is characterized by a balance between birth rates and death rates, resulting in little to no net change in population size.

Front

How does increased industrialization affect habitats?

Back

Increased industrialization typically decreases available habitats due to urban development, pollution, and resource extraction.
