Photosynthesis
What are the inputs of photosynthesis?
Light, carbon dioxide, water
Name 5 nutrients that plants can get from soil.
Nitrogen, phosphorus, oxygen, hydrogen, carbon
What is the carbon cycle?
The rearrangement of carbon as it moves between different areas of Earth.
Why do the number of organisms in each trophic level decrease as you move up through a food chain?
Some energy is lost to the environment each time an organism is consumed/the energy is transferred
Which body part do butterflies taste from?
What are the outputs of photosynthesis?
glucose and oxygen
Organisms - worms, bacteria, fungi, mucilage
Texture
Fertilizer
Which two spheres is carbon moving between when plants photosynthesize?
Name one reason that plant-based foods require less land to produce than animal-based foods. (You cannot say they move)
Animals need food grown for them, plants produce their own food from sunlight, at each level of the food chain energy is lost to the environment, at each level of the food chain organisms require more matter to sustain
What mammal glows under UV light?
What is the overall purpose of photosynthesis?
To create glucose from sunlight energy
What can happen if nutrient run-off from fertilizers get into bodies of water?
Algal blooms can occur, and they can cut off sunlight from aquatic plants. Without the plants, the water cannot be oxygenated, and fish will die.
Name one way that carbon is returned to the atmosphere.
Respiration, decomposition, combustion
Name three criteria to consider when evaluating solutions to food waste issues.
Measurably reduces food waste, collects food waste at an early stage, low natural resource use, low cost, economic potential, recycle or reuse of food waste, practical/easy to establish, food waste and donations are accessible to all communities
How does as turkey vulture defend itself when threatened?
projectile vomit
What organelle does photosynthesis occur in?
Chloroplast
Why do farmers rotate what crops they are putting in a field?
What form is carbon in when it is in the atmosphere?
carbon dioxide
What processes other than photosynthesis do producers need to do to grow and develop.
Cellular respiration and biosynthesis
What animal has the strongest bite on Earth?
What will the glucose be used for after photosynthesis?
Cellular respiration
Predict what would happen if the soil microbes were removed from an ecosystem. Why?
The plants would die. Example: without nitrogen-fixing bacteria, nitrogen is not in a form that is usable by plants.
Other examples will be evaluated as given
What form is carbon stored in after plants do photosynthesis?
glucose
Where does all energy in an ecosystem originate from?
the sun
What metal makes up the enamel of a beaver's teeth, not only making them very strong, but very orange?
Iron
