Basic Ecology
What is the primary source of energy for most ecosystems?
sun
What does the term "biodiversity" refer to?
The term "biodiversity" refers to the variety of living organisms within an ecosystem, including different species of plants, animals, fungi, and microorganisms
Which gaseous substance is most commonly associated with climate change?
Carbon dioxide
What type of waste can be recycled in special plastic containers?
Plastic bottles, food packaging, lids, and containers.
What is the purpose of the 3Rs (Reduce, Reuse, Recycle)?
To promote sustainable resource use
Which gas do plants absorb during photosynthesis?A) Oxygen B) Carbon Dioxide C) Nitrogen D) Helium
Carbon dioxide
Which of the following ecosystems is known to have the lowest biodiversity?A) Coral reef B) Desert C) Tropical rainforest D) Wetland
B) Desert
What natural disasters have become more frequent due to climate change?
More frequent and severe hurricanes, wildfires, droughts, and floods.
What is the term for the process of converting waste materials into reusable materials?
Recycling
Which renewable energy source uses the Earth's internal heat?A) Solar Energy B) Wind Energy C) Geothermal Energy D) Hydropower
C) Geothermal Energy
What is the term for organisms that break down dead plants and animals?
Decomposers / destructors
What is the primary cause of species extinction today?
Human activities
What are main human activities that increase greenhouse gas emissions?
Burning fossil fuels (coal, oil, gas) for energy and transportation.
Deforestation, which reduces the number of trees absorbing carbon dioxide.
What types of pollution cause acid rain, and how does it affect nature?
Air pollution
What is the concept of a "carbon footprint"? A) The amount of water used by an individual or organization B) The total greenhouse gas emissions caused by an individual, organization, event, or product C) The measure of energy efficiency of a building D) The number of trees planted to offset pollution
B) The total greenhouse gas emissions caused by an individual, organization, event, or product
What is the main cause of deforestation?
Human activities
Which biome has the highest biodiversity?
Tropical rainforest
What is the greenhouse effect, and how does it contribute to climate change?
The greenhouse effect is the process by which greenhouse gases (such as carbon dioxide and methane) trap heat in the atmosphere, preventing it from escaping into space. This leads to an increase in global temperature, driving climate change.
What types of waste are considered biodegradable?
Biodegradable waste includes food waste, paper, wood, and other natural materials that can decompose in the environment with the help of microorganisms.
How can renewable energy sources like solar or wind power help reduce climate change?
Renewable energy sources produce electricity without emitting greenhouse gases, helping to reduce the carbon footprint and mitigate climate change.
Which of the following is a renewable resource?1. Solar energy2.Wind energy3. Hydropower4. Biomass5. Geothermal energy
Solar energy
What is the purpose of a wildlife corridor? A) To prevent animals from migrating B) To connect fragmented habitats C) To attract more human activity in the area D) To reduce the need for biodiversity
B) To connect fragmented habitats
How does climate change affect biodiversity in different ecosystems?
Climate change can cause:
Reduction of habitat ranges
Extinction of species unable to adapt to changes in temperature or conditions
Which gas is released during the decomposition of organic waste in landfills? A) Oxygen B) Carbon Dioxide C) Methane D) Nitrogen
C) Methane
What is the concept of a circular economy, and how does it promote sustainability?
A circular economy focuses on reducing waste by reusing, recycling, and sharing resources to create a closed-loop system. This minimizes the environmental impact and promotes sustainability by conserving resources.
