Ecosystems
What is an ecosystem?
An ecosystem is a community of living organisms interacting with their physical environment.
What is pollution?
Pollution is the introduction of harmful substances into the environment.
What is conservation?
Conservation is the protection and management of natural resources to prevent their depletion.
What causes climate change?
Climate change is caused by human activities, such as burning fossil fuels and deforestation, leading to increased greenhouse gases.
Name a renewable resource.
Examples include solar energy, wind energy, or hydropower.
Name a type of biome.
Examples include desert, rainforest, tundra, or grassland.
Name a type of air pollutant.
Examples include carbon monoxide, sulfur dioxide, or particulate matter.
Why is recycling important?
Recycling reduces waste, conserves natural resources, and saves energy.
How does deforestation affect climate?
Deforestation reduces the number of trees that absorb carbon dioxide, increasing atmospheric CO2 levels and contributing to climate change.
What is the importance of trees?
Trees provide oxygen, improve air quality, conserve water, preserve soil, and support wildlife.
What role do producers play?
Producers create energy through photosynthesis, serving as the base of the food chain.
What is a consequence of water pollution?
Consequences include harm to aquatic life, contamination of drinking water, and disruption of ecosystems.
How can we reduce waste?
We can reduce waste by reusing items, composting, and choosing products with less packaging.
What is global warming?
Global warming refers to the long-term increase in Earth's average temperature due to human activities.
How does mining affect the environment?
Mining can lead to habitat destruction, soil erosion, and pollution of nearby water sources.
Describe the water cycle.
The water cycle includes evaporation, condensation, precipitation, and collection.
Describe the greenhouse effect.
Name a method of soil conservation.
Methods include crop rotation, contour farming, and no-till farming.
What are greenhouse gases?
Greenhouse gases are gases that trap heat in the atmosphere, such as carbon dioxide, methane, and nitrous oxide.
What are fossil fuels?
Fossil fuels are natural substances formed from the remains of ancient plants and animals, such as coal, oil, and natural gas.
What is biodiversity?
Biodiversity refers to the variety of life in an area, including the number of species and their interactions.
What are renewable resources?
Renewable resources are resources that can be replenished naturally, such as solar energy, wind energy, and biomass.
What is sustainable development?
Sustainable development is meeting the needs of the present without compromising the ability of future generations to meet their own needs.
What can individuals do to combat climate change?
Individuals can reduce energy consumption, use public transportation, recycle, and support renewable energy initiatives.
What is habitat destruction?
Habitat destruction is the process in which natural habitats are altered or destroyed, leading to loss of biodiversity.
