Which statement BEST explains how energy is transferred in a food web?
- Radiant energy from the Sun is converted into kinetic energy stored in plants, which is then transferred to organisms that eat the plants.
- Thermal energy from the Sun is transferred to organisms that transform it into radiant energy for other organisms.
- The kinetic energy of one organism is transferred to another organism as mechanical energy when it is eaten.
- Chemical energy is transferred from one organism to another based on their feeding relationships.
Chemical energy is transferred from one organism to another based on their feeding relationships.

Identify the 5 layers of the atmosphere and their descriptions
Troposphere - the lowest and densest layer of Earth's atmosphere; contains about 75% of all air and it is where most weather phenomena occur
Stratosphere- the second layer; where the ozone layer is located
Mesosphere - third layer; the coldest and where most meteors burn up.
Thermosphere - fourth layer above earth's surface; second largest layer and has wide temperature range and low air density; where the International Space Station orbits
Exosphere - the highest, largest and least dense layer, it serves as the boundary between Earth and space
