In addition to sunlight, which two substances are the reactants for photosynthesis?
oxygen and water
oatmeal and potato chips
carbon dioxide and oxygen
carbon dioxide and water
Ultimately, all energy for living organisms comes from
french fried potatoes

The process by which plants, some Bacteria, and some Protists make their own food is called __________.
Phototropism
Cellular Respiration
Mitosis
Photosynthesis
What is another word for Reactants?
Products
Raw Materials
Stomata
Pigments
Why is sunlight/ light energy written above the arrow and not as a Reactant?
Sunlight makes plants green and only green plants photosynthesize
Light energy travels through the plant down to the roots and causes the water rise
Sunlight is needed for the chemical reaction in photosynthesis to occur
Light energy can be written as either a Reactant or a Product of photosynthesis

Why are mushrooms important to the food chain?
They recycle nutrients into the ecosystem.
They produce food energy for other living things.
They recycle oxygen into the atmosphere.
They consume excess herbivores in the ecosystem.
Yellowfin tuna, or Thunnus albacores, are large sport fish that are found in tropical and subtropical waters around the world. They typically school under objects such as boats or patches of driftwood for protection from predators. Schooling under these structures also provides yellowfin tuna with easy access to a food source such as smaller herbivorous fish that may be foraging for food around the structures. Which trophic level does yellowfin tuna fill in a food chain?
producer
primary consumer
secondary consumer
tertiary consumer
What is shown in the image below?
food chain
trophic chain
food web
energy web
Which organism is a primary consumer in the food web below?
herbivorous duck
bald eagle
osprey
vegetation
What might happen to the organisms in the food web below if the number of phytoplankton and vegetation drastically decreased?
The small fish and wading birds would be affected.
Only the small fish would be affected.
The small fish, bivalves, and invertebrates would be affected.
The entire food web would be affected.
From the producer level to which level does energy flow directly?
decomposer
tertiary consumer
secondary consumer
primary consumer
The diagram below shows an energy pyramid. In a marine ecosystem, algae carry out photosynthesis. Barracuda eat snapper fish. Reef sharks eat barracuda.
Which organism would be at the top of the energy pyramid?
algae
reef shark
barracuda

What happens during an energy transformation in a living thing?
Energy is created.
Energy is destroyed.
Energy is permanently stored.
Energy changes from one form to another.
What would happen to the bird if the green fish died out?
