EOC Blitz Review - Human Impact and Carbon Cycle

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms. It includes processes like photosynthesis, respiration, decomposition, and combustion.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert carbon dioxide and sunlight into glucose and oxygen. It is a key process in the carbon cycle that removes CO2 from the atmosphere.

Front

What are renewable energy sources?

Back

Renewable energy sources are energy sources that are replenished naturally and can be used repeatedly, such as solar, wind, hydroelectric, and geothermal energy. They help reduce the negative impacts of human activities on ecosystems.

Front

What is habitat fragmentation?

Back

Habitat fragmentation is the process by which large habitats are broken into smaller, isolated patches, often due to human activities like urbanization and deforestation, leading to negative impacts on biodiversity.

Front

What are invasive species?

Back

Invasive species are non-native organisms that, when introduced to a new environment, can outcompete native species for resources, disrupt ecosystems, and reduce biodiversity.

Front

How does pollution affect ecosystems?

Back

Pollution disrupts the balance of ecosystems by introducing harmful substances that can harm organisms, reduce biodiversity, and alter natural processes.

Front

What is the role of decomposers in the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere, and playing a crucial role in nutrient cycling.

Front

What is urbanization?

Back

Urbanization is the process of increasing population density in urban areas, often leading to habitat loss, pollution, and changes in local ecosystems.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases like CO2, which are released through human activities such as burning fossil fuels.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the diversity of species, genetic variation, and ecosystem diversity.
