What are Tertiary Consumers
Carnivore animals that eat the animals that eat the plants.
26
What are quaternary consumers
Animals that feed on tertiary consumers
27
What consumer is considered the top?
Tertiary
28
What is the problem when monoculture
Single crops deplete soil nutrients Lead to soils erosion by wind or heavy rain More susceptible to insects pests and crop diseases
29
Why are synthetic fertilizers a problem?
Pollutes aquatic ecosystem and can’t be recycled
30
2 Reasons as to why pesticides is an unsustainable farming method?
Kills unintended and helpful organisms Toxic chemicals enter the food chain
31
List 4 Unsustainable Farming Methods
Monoculture, Intensive Irrigation, Synthetic Fertilizers, and pesticides
32
What is sustainable agriculture
Provide food for the growing world population
33
Give 4 sustainable argiculture methods
Drip Irrigation Intercropping Crop Rotation Natural Predators
34
What is Bioaccumulation
When harmful substances, like pesticides or heavy metals, build up in an organism’s body over time faster than the organism can get rid of them.
35
When does bioaccumulation occur?
When the chemical is a fat soluble
36
What does burning fossil fuels do?
Increase the number of carbon dioxide in the atmosphere
37
Why is global climate change important
Rising global temperatures Change in global weather patterns Rising sea levels Warm weather leads to increase insect reproduction
38
What does the Fast Pathway affect
Carbon cycles quickly Photosynthesis Cellular respiration
39
What does the Slow Pathway affect
Carbon cycles slowly Fossil fuels Limestone
40
What happens when you move up on a trophic pyramid
Energy decrease Number of individuals decreases Biomass decreases
41
Wat processes do energy capture and conversion occur
Photosynthesis Cellular respiration
42
Wat is photosynthesis?
Plants that capture energy from the sun and store it in the chemical bonds of sugars and other food molecules
43
What is Cellular Respiration?
Organism that release energy stored in the chemical bonds of food molecules they eat and use it as fuel .
44
What are the ingredients for photosynthesis?
Sunlight chlorophyll Water Carbon dioxide
45
What is glucose?
The end product of photosynthesis
46
What does photosynthesis produce
Oxygen fir all organisms on earth
47
What is resilience?
The ability of ecosystems to cope with and recover from damage
48
What 3 things helps with biodiversity and helps in resistance?
Genetic diversity Specie diversity Ecosystem
49
What is bio diversity?
Variety of organisms in the earths ecosystem
50
What is the Ecological footprint?
The calculation of the amount of land, water, energy, and other resources needed to support your personal lifestyle, including the disposal of the wastes your consumption creates
51
Wat are limiting factors that prevent a population from reaching its biotic potential
Interspecies competition Intraspecies competition Disease Predation Disasters Balance other factors such as birth rate, early reproductive age. Effect is to increase death rate Produces S-curve
52
What do population principles depend on?
Biotic Potentail Environmental Resilientence
53
What is Biotic Potential?
Maximum rate a population can increase under ideal conditions
54
What is Environmental Resilience?
Factors that prevent a population from reaching it biotic potential?
55
What are limiting factors that prevent species to continue living?
Interspecies completion Interspecies competition Disease Predation
56
What is the Carrying Capacity?
number of individuals an ecosystem can support indefinitely
57
What does TFR refer to
Total Fertility Rate
58
What happens when you over populate
Exceed the carrying capacity of the environment Run out of resources Population may crash
59
What is a food web
System of connected food chains in an ecosystem
60
What does a food web show
How multiple organism eat/ are eating by different species
61
How is drip irrigation a sustainable agriculture method
Reduces groundwater depletion Minimizes weed growth Reduces water loss do to evaporation
62
How is intercropping a sustainable agriculture method
Growing different types of crops in the same field Reduces soil nutrient depletion
63
What is another name for intercropping
Polyculture
64
How is crop rotation a sustainable agriculture method
Rotate a variety of crops Replenish soil nutrients
65
How is natural predators a sustainable agriculture method
Natural predators versus pesticides
66
Stored
67
What is the mean and what is it good for
Mean is the average set of number
68
Wat is the median?
Odd set of numbers
69
Who do Detritus Food Chain feed on
Any organism on the food chain
70
(Unfinished) =Relationship of Photosynthesis and Cellular Respiration
Photosynthesis gathers energy from the sun which is stored into glucose. Once cellular respiration started it breaks and
71
In Bioaccumulation graph or picture wat has the most and least toxins?
Bottom == least toxins Top=most toxins
72
How does Bioaccumulation differ from energy transfers from a tropic pyramid?
Trophic pyramid= energy decrease Bioaccumulation = as it goes up it increase = opposites
73
How has humans altered the carbon cycle?
Burn fossils, driving cars, and deforestation = removing a storage container for carbon dixoixed and is then released into the atmosphere.
74
What can we do to prevent/ fix climate change
Use solar/ wind energy Use energy saving appliances
75
Who prioritizes the ecological footprint
