All food webs and food chains begin with _________________.
primary consumer
producers
secondary consumers
tertiary consumers
Which organism is the carnivore?
Which organism is the omnivore?
Based on the image, which organism recieves the least amount of energy from the producer?
Owl
Grasshopper
Lilypad
Mouse
How are primary consumers different from secondary consumers?
Primary consumers eat only plants; secondary consumers eat other consumers.
Primary consumers eat other consumers; secondary consumers eat only plants.
Primary consumers eat plants and other consumers; secondary consumers eat plants and decompose matter.
Primary consumers eat plants and decompose matter; secondary consumers eat plants and other consumers.
A decreases in the grass population will most immediately decrease the available energy for the
snake
deer
mouse
frog
Using food web which of the following is a secondary consumer?
snake
worm
butterfy
squirrel
Using food web which of the following is a secondary consumer?
snake
worm
butterfy
squirrel
Using the food web which of the following is a tertiary consumer?
frog
bird
eagle
worm
Using the food web what would happen if the eagle became extinct?
The frog population would decrease.
The frog population would increase.
The butterfly population would increase.
The snake population would decrease.
Which group is not represented in the food web?
producers
primary consumers
secondary consumers
decomposers
The diagram provided shows a simple food web. Which group of organisms is not represented in the diagram?
prey
decomposers
consumers
producers
Look at the diagram of the food web. The arrows means “eaten by.”
What will happen if the number of snakes goes down?
The owl will eat the grass
The number of frogs will go down
The hawk and owl will have less food
The number of mice and grasshoppers will go up.
The transfer of energy from one organism to the next in an ecosystem begins with a producer. A producer is an organism that produces its own food. A consumer is an organism in a food chain that obtains energy from producers or other consumers; consumers may be herbivores or carnivores.
Which food chain correctly describes the flow of energy in an ecosystem?
grass → grasshopper → fish → human
grasshopper → fish → human
human → fish → grasshopper
human → grasshopper → fish → grass
The food chain is--
The movement of water from the surface to the atmosphere.
The path of food energy from one organism to another.
The ranking of organisms by size in an ecosystem.
A list of food that consumers will eat in an ecosystem.
What is most likely the first thing to result from having fewer field mice in the food chain pictured here?
The snakes would have to find another food source.
The plants that make seeds would decrease in number.
The eagles would have to fly away to a location.
The mice would eat many more kinds of seeds.
Interactions in an ecosystem result from the transfer of matter and energy from producers to consumers and eventually decomposers. What are the forms of energy transfer from numbers 1 through 4?
Chemical energy to chemical energy
Light energy to chemical energy
Chemical energy to heat energy
Heat energy to mechanical energy
