How much energy gets passed up the energy pyramid
10% of the original energy gets passed up per level
100
Formula for photosynthesis
6H₂O + 6CO₂ + Light Energy → C₆H₁₂O₆+ 6O₂
Water + carbon dioxide--> glucose + oxygen
100
State what occures in the troposphere
Atmospheric layer where weather occurs
100
A line randomly crosses a space and any organisms that are close to the line are counted. What kind of sampling is this?
transect sampling
100
Describe the tropical grassland
grasses and scattered trees adapted to a tropical wet and dry climate
200
List the trophic levels
Primary producers, primary consumer, secondary consumer, tertiary consumer, decomposers
200
State the formula for cellular respiration
oxygen + glucose > carbon dioxide + water + energy
200
What is the function of ozone layer
Keeps most UV light from reaching Earth
200
What is the capture-mark-recapture method and what is it used for?
The method involves capturing a number of animals, marking them, releasing them back into the population, and then determining the ratio of marked to unmarked animals in the population. Also known as The Lincoln Index, a process which is used to estimate the size of populations which are very mobile and difficult to survey.
200
Which biome experiences very little rainfall with soils rich in minerals but poor in nutrients. temperature, elevation, and latitude can vary greatly
Desert Biome
300
What is the energy pyramid
A diagram that shows the amount of energy that moves from one feeding level to another in a food web
300
State the Lincoln Index
300
What are the main gasses of the atmosphere
nitrogen • oxygen • carbon dioxide • argon • water vapour
300
What is the kick sampling method
Used to study river organism, sediment is kicked up and a net downstream catches any organisms for a set period of time.
300
Describe the rainforest biome
year round warmth and high rainfall levels. almost all lie near the equator in South America, central Africa and southern Asia. Very nutrient poor soil.
400
What is the pyramid of biomass
A pyramid that illustrates the total mass of all the organisms in a trophic level
400
State the Simpson's Index of Diversity
400
Location and function of Ozone layer
Located in stratosphere and keeps most UV light from reaching Earth
400
What are light traps used for?
A method of sampling populations of night-flying organisms that are attracted to lights, especially moths.

Describe the tropical grassland
grasses and scattered trees adapted to a tropical wet and dry climate
500
What is the pyramid of numbers
Representation of the number of individual organisms in each trophic level of an ecosystem
500
State the formula for aerobic respiration
C6H12O6 + 6O2 --> 6CO2 + 6H20 + energy
Glucose + oxygen-->carbon dioxide+ Water + ATP
500
What is the greenhouse effect and its role in maintaining Earth's temperature
Greenhouse gasses are gases in the atmosphere, it absorbs some of this infrared radiation and prevent it from leaving the atmosphere
500
Describe point quadrats and beifly explain what they are used for
A horizontal bar on two legs with a series of holes set at intervals along its length, through which pins are dropped. Can be used to investigate the abundance and distribution of organisms in an area.

Describe the tundra biome
very short cold summers and very long and extremely cold winters with strong winds and little precipitation. contains permafrost
