Producers are located where in a food pyramid?
The bottom; the greatest group and the most important.
What ocean do we swim in living in Florida?
What ocean would you swim in if you went to California?
Atlantic Ocean. Pacific Ocean.
The process by which plants derive their energy
Photosynthesis
What is Plastic made of?
Oil
What pigment makes plants appear green?
Chlorophyll.
This organism cannot make its own energy and eats only plants for its energy. What trophic level does it belong to?
Herbivore. Primary Consumer.
Describe the difference between an object that is transparent, translucent, and opaque. Give an example for each.
Light completely passes through a transparent object; Glass window.
Light partially passes through a translucent object; Wax Paper.
Light does not pass through an opaque object; Stone.
What are the Reactants and Products of the process by which plants derive their energy?
6CO2 + 6H2O → C6H12O6 + 6O2
Reactants: Carbon Dioxide and Water
Products: Glucose (sugar) and Oxygen (byproduct)
What is the difference between nonrenewable and renewable energy? Give two examples for each.
Nonrenewable energy sources are finite; Renewable energy sources are infinite. Oil, Nuclear, etc/ Hydroelectricity, Solar, Geothermal, etc
Name two greenhouse gases.
CO2 , CH4 , N2O
What does the arrow in food chains represent?
The flow of energy and who is eating who.
In regards to a wave, what is the crest, wavelength, trough, and amplitude?
Show picture.
What is the difference between an autotroph and heterotroph? Give an example for each.
Autotrophs are known as producers because they are able to make their own food from raw materials and energy. Examples include plants, algae, and some types of bacteria. Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs.
What kind of energy type is Natural Gas?
Nonrenewable.
What does pH stand for? What is the ideal pH of water?
Potential of Hydrogen. 7.
What organisms roughly produce 50% of the oxygen on Earth?
Oceanic plankton — drifting plants, algae, and some bacteria that can photosynthesize.
Explain why the appearance of a straw in a glass of water looks shifted.
Light bends when it passes from one medium (air) into another medium of a different density (water); slows speed. This bending of light, called refraction, causes the straw to look broken.
Name the plant cell organelle that converts light energy into relatively stable chemical energy via the photosynthetic process.
Chloroplast
What process do atoms undergo in order to create Nuclear energy? What element is typically involved?
Nuclear fission using Uranium atoms.
By which process is Natural Gas extracted?
Hydraulic fracturing, or fracking.
What percentage of energy is transferred from a lower trophic level to a higher trophic level?
10%.
Give an example of a longitudinal wave and a transverse wave.
Longitudinal- Sound Waves
- the particles are displaced parallel to the direction the wave travels.
Transverse- Light Waves
- the particles are displaced perpendicularly to the direction the wave travels.
Carbon dioxide enters the leaf through small
openings called _____.
Stoma
This country generates over 99% of its electricity from renewable sources, namely hydroelectricity (approximately 80%) and geothermal (approximately 20%).
Iceland because of its geographical position; a very active volcanic zone that powers its geothermal systems.
This plant vascular tissue conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support.
Xylem.
