What do we call the organisms that start the food chain ?

Producers/Autotrophs

300

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. 

400

Put the following terms in order from the lowest level to the highest level:

If the primary consumer has 12,000 kJ of energy available to them. How much energy was produced by the producers?

120,000 kJ

Photosynthesis & Respiration

100

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.

200

Why are photosynthesis and cellular respiration complementary processes ?

Because one process uses the products of the other to start

300

Which part of the leaf has a similar function as the nose for humans ?

Stoma/Stomata 

400

What is the difference between chloroplast and chlorophyll 

Chloroplast is where the photosynthesis happens, and chlorophyll is the pigment that performs the photosynthesis 

500

How many carbons are involved 1 photosynthesis/respiration cycle ?

6

300

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

400

What are the 3 things that the ecosystem needs in order to be self-sustaining. 

Capture Energy

Transfer Energy

Cycle Nutrients

500

Describe 2 ways water from the soil can return to the atmosphere 

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

Aquatic Ecosystem

100

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

Carbon Cycle

100

Name 2 of the places where we can find inorganic carbon

Think about "Land, Sea and Air"

-Atmosphere

-Ocean

-Earth's crust 

200

Name 2 places where we can find organic carbon

Any 2 of the following:

Living things

In bogs (dead/decayed organisms)

Fossil Fuels

300

What are the four major carbon cycle reactions

1. Photosynthesis

2. Cellular Respiration

3. Combustion

4. Decay/Decomposition

400

Name 2 of the organic carbon molecules we find in living organisms.

Any 2 of the following:

Carbohydrates (Sugar), Proteins, Fats, DNA

500

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.
