What is the equation for photosynthesis?
CO2 + H2O --> C6H12O6 + O2
100
What is the equation for cellular respiration?
C6H12O6 + 6O2 ---> 6CO2 + 6H2O + Energy(ATP)
100
What is the type of organism at the beginning of a food chain/food web?
Primary Producer
100
What is meant by natality?
Births
100
How would developing a single plastic that can be modified for many different uses effect the rate of plastics recycling?
It would increase recycling.
200
Which wavelength of light is least effective in promoting photosynthesis in green plants according to the action spectrum (light spectrum)?
The light wavelength 550nm
200
What are the products for the cell respiration reaction equation?
6CO2 + 6H2O + energy(ATP)
200
How much energy is transferred from one trophic level to the next in a food web?
10%
200
What is meant by the term mortality?
Deaths
200
The precautionary principle says "introducing new product or process whose ultimate effects are disputed or unknown, should be resisted". If evidence suggests that the Ebola virus is transmitted through animal products, what should be done when enacting the precautionary principle?
Trading in animal products should be banned.
300
What would a graph look like which best represents the effect of temperature on the rate of photosynthesis?
Low on the left going to high in the middle and low on the right
300
What are the reactants for the cell respiration reaction?
C6H12O6 + 6O2
300
Why do food chains rarely contain more than 5 organisms?
The conversion of food into growth is not very efficient.
300
What does immigration mean?
Moving into an area.
300
What are the most abundant greenhouse gases?
Water vapor, carbon dioxide, methane, and oxides of nitrogen
400
What are the products in the photosynthesis reaction equation?
C6H12O6 + 6O2
400
What is the effect of increasing concentration of carbon dioxide?
It increases the dissociation of oxygen from haemoglobin at respiring tissues.
400
How do you calculate percentage change.
First: work out the difference (increase) between the two numbers you are comparing. Second: divide the increase by the original number and multiply the answer by 100. If your answer is a negative number then this is a percentage decrease.
400
What is the S shaped curve called?
logistic growth curve
400
In the carbon cycle, what causes carbon dioxide to move to carbon compounds in producers?
Photosynthesis
500
What are the reactants in the photosynthesis reaction equation?
6CO2 + 6H2O
500
Why does warm water hold less oxygen?
Warm water has more space between water molecules allowing oxygen to escape.
500
How much energy is transferred from first to the last organism in a food chain with 5 organisms?
0.01%
500
In the S shaped logistic growth curve, when is natality plus immigration greater than mortality plus emigration.
Where the line is going up from left to right.
500
In the carbon cycle, what causes carbon in carbon compounds and carbon in deposits to move to carbon dioxide?
Combustion
