1.
What is the difference between a consumer and a producer?
Consumers and producers are the same thing.
Producers are organisms that eat other organisms. Consumers are organisms that make their own food.
Producers are organisms that eat both plants and animals. Consumers only eat plants and are vegan on Sunday.
Consumers are organisms that eat other organisms. Producers are organisms that make their own food using the energy from the sun.
2.
One molecule of glucose is recycled into ___ molecules of carbon dioxide during cellular respiration
1
6
12
2
3.
Which time of consumers is found the top of the food chain?
Primary Consumer
Decomposer
Tertiary consumer (apex predators)
Producer
4.
How does carbon stored in the bodies of living organisms move into rocks?
Living organisms die and decay releasing carbon into the soil. The soil is compacted into rocks.
Carbon dioxide released through respiration (breathing) dissolves into certain rocks like limestone.
Carbon dioxide dissolves in ocean water and is slowly absorbed by rocks in the ocean
Living organisms decay and become fossil fuels and those fuels are used to power rock making machines!
5.
Living organisms can incorporate _______ into their metabolisms
nitrogen gas
nitrates
helium
ammonia
6.
What is the primary role of a decomposer in an ecosystem?
The break apart dead organisms into simpler organic material which creates nutrients for producers
They produce their own energy and begin each food chain
They are the apex predators in each ecosystem
They serve no purpose in an ecosystem
7.
Every food chains begins with a ____________
8.
Which statement is true?
Food chains are the best depictions of feeding relations because they show one path of energy flow
Food webs are the best depictions of feeding relationships because they show the many ways that plants and animals are connected.
Food chains are the best because they are simple.
Food webs and food chains are equally unhelpful. This is why food hexagons should be used because they show the hexagonal relationship between plants and animals.
9.
The three steps of the nitrogen cycle in order, starting with nitrogen gas in the atmosphere, are

Herbivore
Omnivore
Animalplantivore
11.
The nitrogen cycle requires _____ to convert nitrogen to nitrites and nitrates.
bacteria
plants
animals
legumes
12.
Which role does photosynthesis play in the flow of energy?
It helps plants break down glucose to use for energy
It provides radiant energy to all of the organisms in the entire food chain.
It converts radiant energy from the sun to chemical energy to be used by organisms in the food chain.
It allows plants to create energy for themselves to store and use for metabolism
13.
How do energy and matter move in ecosystems?
Matters flows in one direction and energy cycles through the environment
Energy flows in one direction and matter cycles through the environment
Energy and matter move freely throughout the ecosystem.
Energy and matter flow in only one directions
