Why do urbanisation and deforestation make flooding more likely? Earthquake Hazards Is Singapore threatened by earthquakes? Can we predict earthquakes? Why does a building on solid bedrock resist better to an earthquake than a building on sediment or reclaimed land? Why does a building with base isolation resist better to an earthquake than a building without base isolation? Why does a building with full bracing resist better to an earthquake than a building with no bracing?
Impacts of Volcanic Hazards What are the principal signals of a volcanic unrest? How can we forecast volcanic eruptions?
Tsunamis Where is a tsunami most likely to happen? Can Singapore be affected by a tsunami? Can animals sense an impending tsunami? What should we do during a tsunami? Why do trees seem to resist more to tsunamis than houses? Why does a boat at sea experience a tsunami differently from a boat near the shore?
Volcanoes All About Volcanoes What is the difference between magma and lava? Is lava always liquid? What does a magma chamber look like? What are the largest eruptions in the world? Are earthquakes and volcanic eruptions related?
We can thank photosynthesis for bread! Wheat grains, like the ones pictured, are grown in huge fields.
When they are harvested, they are ground into a powder that we might recognize as flour. Humans, other animals, fungi, and some microorganisms cannot make food in their own bodies like autotrophs, but they still rely on photosynthesis. Through the transfer of energy from the Sun to plants, plants build sugars that humans consume to drive our daily activities. Even when we eat things like chicken or fish, we are transferring energy from the Sun into our bodies because, at some point, one organism consumed a photosynthetic organism e.

They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.
These primary producers form the base of an ecosystem and fuel the next trophic levels. Without this process, life on Earth as we know it would not be possible. We depend on plants for oxygen production and food. Learn more about this vital process with these classroom resources. Chlorophyll is a pigment that gives plants their green color, and it helps plants create their own food through photosynthesis.
What does a plant leaf have to do with the solar energy panels on the White House? Producers convert water, carbon dioxide, minerals, and sunlight into the organic molecules that are the foundation of all life on Earth.

The process During photosynthesis, plants take in carbon dioxide CO 2 and water H 2 O from the air and soil. Chlorophyll Inside the plant cell are small organelles called chloroplasts, which store the energy of sunlight. Light-dependent reactions vs.
