Food Chains
Carbon Cycle
Producer & Consumers
100
a model that shows how the energy available to organisms at each trophic (feeding) level of an ecosystem is decreased
Energy Pyramid
100
This is the original source of energy for most food webs.
The sun
100
What is the original source of energy for most food chains? (before producers)
Sunlight
100
process of carbon converting and recycling through the environment and living organisms
Carbon Cycle
100
This is the term for a consumer that only eats other animals.
Carnivores
200
The second level on the energy pyramid is known as?
Primary Consumer
200
The organisms at the top of the food web that have no natural predators.
Apex predator
200
A linear sequence of organisms through which nutrients and energy pass
Food Chain
200
Animals release carbon dioxide back into the atmosphere through this process.
Respiration
200
Whose role is it to breakdown dead organisms and recycle nutrients?
Decomposers
300
What level of the energy pyramid provides the most energy?
Primary Producer
300
In this food web the snake would be considered a ....?
Tertiary Consumer
300
What type of consumer is a wolf that eats a rabbit?
Secondary Consumer
300
Burning fossil fuels releases this gas into the atmosphere, contributing to climate change.
Carbon Dioxide
300
organisms that eat only plants (primary consumers)
Herbivores
400
This is the reason why only about 10% of energy is passed from one trophic level to the next in an energy pyramid.
energy is lost as heat and used for life processes
400
Which of the following would have the greatest impact on the food web if it were removed?
Oak Tree
400
A rabbit eats grass, and a fox eats the rabbit. What level is the rabbit in the food chain?
grass → rabbit → fox
Primary Consumer
400
This process removes carbon dioxide from the atmosphere and turns it into glucose using sunlight.
Photosynthesis
400
make food for themselves using light energy, carbon dioxide, and water (another name for producer)
Autotroph
500
How much energy is lost as you move up the energy pyramid?
10%
500
This term describes when one organism eats another and energy is transferred in the food web.
Trophic Interaction
500
What is the herbivore in the food chain above?
Grasshopper
500
What does the arrow from the cow represent?
Carbon Dioxide being released back into the atmosphere
500
How do producers gain energy?
Get energy from sunlight and produce their own food
