What does biodiversity mean?
The variety of species in an ecosytem
100
What is the main source of energy for any food chain?
The sun
100
What is a food web?
A diagram showing the feeding relationships in an ecosystem.
100
What are the 4 cycles of matter?
Hydrological (water), Carbon, Nitrogen, Phosphorus
100
What are the 3 layers that make up the biosphere?
lithosphere, hydrosphere, and atmosphere
200
What does a high amount of biodiversity mean about the ecosystem?
It means that it is functioning well. There is enough food/energy available for many organisms to survive.
200
What happens to energy as it moves through a food chain?
Only about 10% is passed on. Energy is lost due to metabolism, reproduction, wastes, cell growth, respiration, general body maintenance
200
List 4 components of a food chain.
producer, decomposer, energy source, primary/secondary/tertiary consumers, herbivore, carnivore, omnivore
200
Why is water important to living things?
Helps with cell growth and repair, maintains body temp., allows cells to divide..
200
What are 3 primary consumers that we would find around the Tsuu T'ina Reserve?
Rabbits, Foxes, Magpies, Squirrels, Birds, Catepillars, etc..
300
Which ecosystem has the highest amount of biodiversity?
The rain forest
300
What's another term for an autotrophic organism?
A producer
300
Carnivores are classified as secondary consumers, because they eat.
Primary consumers
300
Where is the largest reservoir (storage) for Phosphorus?
In the Earth's crust/rocks
300
Draw a food web (on the board) with at least 7 organisms. Make sure to include producers, consumers and predators
Answers will vary

How can having a large amount of biodiversity protect an ecosystem from environmental damage?
The food webs are larger and more complex. There is a wide variety of species. There is an abundance of food.
400
Without this, a food chain wouldn't be able to operate.
A Decomposer
400
What is a difference between a food chain and a food web?
Food chains are linear (straight lines) that show energy transfer. Food webs are more complex and show feeding relationships among organisms.
400
What are two ways that Carbon gets released into the atmosphere?
Respiration/photosynthesis and burning of fossil fuels

If a berry produces 100000 KJ of energy how many would a bear have to eat to get 5000 KJ of energy?
10000 x .10 = 10000 50000 / 1000 = 50 berries
500
What are 3 causes of biodiversity loss today?
Over hunting, deforestation, climate change, invasion of non-native species, pollution, forest fires
500
In a typical ocean ecosystem, list a producer, primary consumer, secondary consumer and top carnivore
phytoplankton, algae, seaweed, kelp - producers zooplankton, any small fish - primary consumer bigger fish, coral, whales, seals - secondary consumer shark, killer whale - top carnivore
500
Of the following organisms, which one is considered an omnivore? owl, red fox, rabbit, black bear and deer
The black bear (eats berries/plants and meat)
500
What two chemicals mix together to make acid rain?
Sulpher Dioxide and Nitrogen (NO2, NO3)

Explain the first two law of Thermodynamics
Energy cannot be created or destroyed In the process of energy transfer, some energy is lost (as heat)
