What is the meaning of Biocapacity?

• The capacity of the natural world to produce and reproduce resources for us humans only

• The capacity of a given biological area to generate an ongoing supply of renewable resources and to absorb its waste.

• The capacity of the area to supply humans with their lifestyles

• The capacity of the natural world to look after itself

Answer explanation

Biocapacity refers to the ability of a biological area to produce renewable resources and manage waste, making the second choice correct. It emphasizes sustainability and the balance of resource generation and waste absorption.

How does biocapacity relate to ecological footprint?

• Biocapacity measures the ecological footprint of a single individual.

• Biocapacity is the same as ecological footprint.

• Biocapacity is the ability of an area to support the ecological footprint of its population.

• Biocapacity and ecological footprint are unrelated concepts.

Answer explanation

Biocapacity refers to the capacity of an area to generate resources and absorb waste, thus supporting the ecological footprint of its population. This means it directly relates to how well an area can sustain its inhabitants' resource use.

What factors can affect the biocapacity of a region?

• Climate change and land use practices.

• Only the population size.

• None of the above.

• Technological advancements alone.

Answer explanation

The biocapacity of a region is influenced by various factors, primarily climate change and land use practices, which affect resource availability and ecosystem health. Population size and technology also play roles, but are not the sole factors.

Why is it important to maintain a balance between biocapacity and consumption?

• To increase the population size indefinitely.

• To reduce the need for technological innovation.

• To eliminate the need for renewable resources.

• To ensure sustainable development and prevent resource depletion.

Answer explanation

Maintaining a balance between biocapacity and consumption is crucial for ensuring sustainable development and preventing resource depletion, which helps protect ecosystems and supports future generations.

What is the process that keeps the planet warm?

• The Greenhouse Effect

• The GreenShoot Effect

• Global Warming

• Global Greenhouse Effect

Answer explanation

The Greenhouse Effect is the process that keeps the planet warm by trapping heat from the sun in the atmosphere. This natural phenomenon is essential for maintaining Earth's temperature, unlike the other options listed.

What is the primary cause of the increase in greenhouse gases?

• Human activities such as burning fossil fuels

• Natural volcanic eruptions

• Solar flares

• Ocean currents

Answer explanation

The primary cause of the increase in greenhouse gases is human activities, particularly the burning of fossil fuels. This process releases significant amounts of carbon dioxide and other greenhouse gases into the atmosphere.

How can individuals reduce their ecological footprint?

• By increasing energy consumption

• By using public transportation and reducing waste

• By ignoring recycling practices

• By consuming more non-renewable resources

Answer explanation

Individuals can reduce their ecological footprint by using public transportation, which lowers carbon emissions, and by reducing waste, which minimizes resource consumption and landfill impact.

What is the relationship between deforestation and biocapacity?

• Deforestation decreases biocapacity by reducing the ability to absorb CO2.

• Deforestation only affects urban areas.

• Deforestation has no impact on biocapacity.

• Deforestation increases biocapacity by creating more land for agriculture.

Answer explanation

Deforestation decreases biocapacity because it reduces the number of trees available to absorb CO2, which is crucial for maintaining ecological balance and supporting life.

What does carbon dioxide do with the radiation coming from the sun?

• It reflects the radiation back down towards earth

• It lets the radiation just flow through it

• The radiation is keeing the planet warm

Answer explanation

Carbon dioxide traps some of the sun's radiation, preventing it from escaping back into space, which helps keep the planet warm. It does not reflect radiation back down; instead, it absorbs and re-emits it.

What is another important greenhouse gas?

• Air

• Methane

• Oxygen

• Nitrogen

Answer explanation

Methane is a significant greenhouse gas, contributing to climate change. While oxygen and nitrogen are abundant in the atmosphere, they do not have the same warming effect as methane, making it the key correct answer.
