The fennec, arctic, and gray foxes have different appearances because
they belong to different kingdoms
they have adapted to different environments
they are hybrids of two different species
their appearances change from season to season
Which statement about adaptations is true?
Adaptations include body structures but not behaviors.
Adaptations occur when one individual develops better survival characteristics.
Adaptations develop during the lifetime of an individual.
Adaptations occur when survival characteristics are passed from one generation to another.
What happens to a species that cannot adapt to changing conditions in its environment
The individual organisms die
The species may become extinct.
The species moves to another environment.
The individual organisms move to other environments
Which type of organisms get energy by breaking down the remains of dead organisms?
parasites
producers
consumers
decomposers
How is a food chain related to a food web?
They are not related
Food chains make up a food web
Food webs make up a food chain.
Food webs run parallel to food chains
An organism that harms another in a symbiotic relationship is a
prey
polluter
parasite
predator
What type of interaction does the diagram above show?
food web
food chain
energy pyramid
energy chain
Why does the amount of available energy decrease at higher levels of the energy pyramid?
the upper-level organisms do not need as much energy.
There are more upper-level organisms than lower-level organisms
Other substances move up the pyramid and take away some of the energy.
Some energy is used by organisms at each level for their own life processes
When different species with similar needs live in an ecosystem with limited resources, what will happen?
They will live peacefully together.
They will compete for available resources.
Some organisms will become prey and eat other organisms.
One species will adapt so that they will have different needs.
Barnacles live on the side of a whale. The barnacles benefit but do not help or harm the whale. What kind of relationship is this?
parasitism
symbolism
mutualism
commensalism
Which of the following would be the most useful adaptation for prey?
a keen sense of smell
strong jaws and sharp teeth
the ability to look like a stick or a rock
a poisonous bite that can paralyze another organism
As bees collect nectar from flowers, they spread pollen from one flower to another. Both species benefit. Which type of relationship is this?
succession
parasitism
mutualism
commensalism
In the nitrogen cycle, where do animals get their nitrogen?
from plants
from the sun
from the air
from decomposers
Why are photosynthesis and respiration such important parts of the carbon cycle?
Photosynthesis produces the carbon dioxide that animals breathe.
Animals breathe out the oxygen that plants need for photosynthesis.
Photosynthesis processes carbon dioxide into oxygen that animals breathe
Animals take in carbon dioxide and process it into the carbon that plants need for photosynthesis.
What does a food chain show?
the path in which energy flows
all the animals eaten by other animals
the amount of energy transferred from organism to organism
how chains are made
What does an energy pyramid show that a food chain does not?
the direction of energy flow
all the animals an organism eats
egyptians
the decrease of energy as it passes
Which of these is an abiotic factor in an ecosystem?
bird
cactus
soil
snake
A population includes
only members of a single species
both abiotic and biotic factors
all the living things in an ecosystem
all the nonliving things in an ecosystem
Which of the following organisms is a producer?
bird
squirrel
deer
tree
How are decomposers and consumers similar?
They both carry out photosynthesis
They cannot make their own food
They are not part of a food chain
They are both producers
An animal with a thick layer of blubber and thick fur is best suited to survive in
a hot environment
a dry environment
a rainy environment
a cold environment
Some organisms such as dolphins have streamlined bodies that allow them to
breath underwater
keep a constant body temperature
move swiftly in the water
communicate with other dolphins
Fur color, long limbs, strong jaws, the ability to run fast are all examples of
behavioral adaptations
structural adaptations
Wolves traveling in packs, migration, hibernation are all examples of
behavioral adaptation
structural adaptations
