What is another name for consumers ?
Herterotrophs
Why is it a good idea to walk around in a forest/natural habitat once in a while ?
Because there is more oxygen supply in those areas.
What percentage of the nutrients move to the next level of the food chains ?
10%
What percentage of Earth's water are in the form of fresh water ?
About 3%
Name 2 of the places where we can find inorganic carbon
Think about "Land, Sea and Air"
-Atmosphere
-Ocean
-Earth's crust
What do we call the organisms that start the food chain ?
Producers/Autotrophs
Why are photosynthesis and cellular respiration complementary processes ?
Because one process uses the products of the other to start
Where are most of Earth's fresh water source located ?
Glaciers/Ice in the Arctic
Name 2 places where we can find organic carbon
Living things
In bogs (dead/decayed organisms)
Fossil Fuels
What is the difference between primary, secondary, and tertiary consumers ?
Primary consumers consume the producers, and secondary consumers consume the primary consumers, and tertiary consumers consume all other consumers.
Which part of the leaf has a similar function as the nose for humans ?
Stoma/Stomata
Name 3 Processes in the Water Cycle for water to move from one place to another
Any 3 of the following:
Condensation
Evaporation
Precipitation
Runoff
Transpiration
What are the 4 major basic needs for an aquatic ecosystem ?
CO2
O2
Sunlight
Nutrients
What are the four major carbon cycle reactions
1. Photosynthesis
2. Cellular Respiration
3. Combustion
4. Decay/Decomposition
Community, Population, Organisms, Biome, Ecosystem, Biosphere
Organism--> Population--> Community--> Ecosystem--> Biome --> Biosphere
What is the difference between chloroplast and chlorophyll
Chloroplast is where the photosynthesis happens, and chlorophyll is the pigment that performs the photosynthesis
What are the 3 things that the ecosystem needs in order to be self-sustaining.
Capture Energy
Transfer Energy
Cycle Nutrients
What are the 3 main fresh water ecosystems
River/Streams
Lakes & Ponds
Bogs/Marshes
Name 2 of the organic carbon molecules we find in living organisms.
Any 2 of the following:
Carbohydrates (Sugar), Proteins, Fats, DNA
If the primary consumer has 12,000 kJ of energy available to them. How much energy was produced by the producers?
120,000 kJ
How many carbons are involved 1 photosynthesis/respiration cycle ?
6
Route 1:
Run-off into lake/pond and then evaporate back to the atmosphere.
Route 2:
Water from soil gets absorbed by the plants, and the water returns to the atmosphere via transpiration
Name 2 human activities that can alter the aquatic ecosystem
Any 2 of the following:
-Replacing natural vegetation along the shoreline
-Removing sand/sediment along the shoreline
-Over-building and over-mining
-Overfishing
-draining wetlands
What are two ways that carbons from animals can return back to the atmosphere.
Route 1:
Directly through cellular respiration, CO2 is exhaled and returned to the atmosphere.
Route 2:
Animals die and decay into fossil fuels and later combusted to be returned to the atmosphere.
