What type of fuel source causes deforestation?

Back

Biomass is a fuel source that can lead to deforestation due to the need for land to grow the biomass crops.

Front

What describes the birth and death rate of Stage 2 of the Demographic Transition Model (DTM)?

Back

In Stage 2 of the DTM, the death rate is decreasing while the birth rate remains high, leading to population growth.

Front

Which of the following is NOT a non-renewable energy source?

Back

Biomass is considered a renewable energy source, unlike uranium, coal, and natural gas.

Front

What growth model is represented by an S-shaped curve?

Back

The logistic growth model is characterized by an S-shaped curve, indicating population growth that levels off as resources become limited.

Front

What is the main cause of coral bleaching?

Back

Higher ocean temperatures are the primary cause of coral bleaching, leading to the expulsion of symbiotic algae from coral.

Front

Define non-renewable energy sources.

Back

Non-renewable energy sources are those that cannot be replenished in a short period of time, such as fossil fuels and nuclear energy.

Front

What is the significance of the logistic growth model in ecology?

Back

The logistic growth model helps to understand how populations grow in an environment with limited resources, showing how growth slows as it approaches carrying capacity.

Front

Explain the concept of deforestation.

Back

Deforestation is the large-scale removal of trees from forested areas, often resulting in damage to the quality of the land.

Front

What are the environmental impacts of biomass energy?

Back

Biomass energy can lead to deforestation, habitat loss, and increased greenhouse gas emissions if not managed sustainably.

Front

What is coral bleaching?

Back

Coral bleaching occurs when corals lose their color due to stress factors like increased water temperature, leading to the loss of symbiotic algae.
