What is the definition of biotic?
living things in an ecosystem
nonliving things in an ecosystem
a characteristic that helps an organism survive and reproduce in its environment
squirrels
What is the definition of abiotic?
non-living things in the ecosystem
producers
the place in an ecosystem where an organism lives
population
Define "habitat."
the path of food energy from the sun to the producer to a series of consumers (showing the feeding relationships in an ecosystem)
all organisms of the same species that live in the same place at the same time
the place in an ecosystem where an organism lives
all organisms of the same species that live in the same place at the same time
Define "food chain."
a large region of land with a distinct climate and certain types of plant and animal life
all organisms of the same species that live in the same place at the same time
the part of the Earth that is able to support life
the path of food energy from the sun to the producer to a series of consumers (showing the feeding relationships in an ecosystem)
How does energy transfer through the levels of the energy pyramid?
Energy flows from smaller organisms to larger ones.
Energy moves down through the energy levels of the food pyramid
Energy moves up through the energy levels of the food pyramid.
Energy moves from warm blooded organisms to cold blooded ones.
What does it mean to say there is equilibrium within an ecosystem?
There are equal numbers of male and female organisms
There are equal numbers of plants and animals
A state of balance where the types of species living in an area are not changing rapidly.
The ecosystem is unbalanced.
Which ecosystem most likely has the greatest biological diversity and therefore the highest sustainability?
a pine tree in which three groups of birds live
a rainforest that has many different types of plants and animals
a tundra region that has many penguins
a tank that includes several goldfish
Which of the following is an example of an interaction between a biotic and abiotic factor in an ecosystem?
A deer drinks from a pond.
A robin lays eggs.
A fish eats an insect.
Bacteria break down the remains of a dead plant
Each level of organization in an ecosystem is made up of parts. In a diagram of a coral reef ecosystem, which of the following is an example of the population level of organization?
A group of sea anemones
a colony of coral and a stand of sea grass
seawater
a clown fish
Which of the following statements best describes the relationship between ecosystems and biomes?
An ecosystem may contain many biomes, and biomes within the same ecosystem are typically home to similar species of organisms.
A biome may contain many ecosystems, and ecosystems within the same biome are typically home to similar species of organisms.
Both biomes and ecosystems are characterized by their climate conditions and the communities that live in them; however, biomes refer to land environments and ecosystems refer to aquatic environments.

Which of the following is an example of an abiotic factor in an ecosystem?
roots
grass
birds
sunlight
All the different populations that live together in an area make up a(n)-
community
biome
ecosystem
biosphere
They are all the living and nonliving things in an area such as the animals, plants, water, soil, air , and sunlight together.
environment
community
ecosystem
population
Look at the picture. What kind of organization is the following.
nonliving things
population
community
endangered species
All the organisms that live in this place shown in the picture form this.
niche
population
community
habitat
This kind of living thing makes its own food through a process called photosynthesis. It is the first level of organization in a food chain.
consumer
producer
decomposer
fungi
Look at the image that shows the transfer of energy in a sequence of living things. This represents one in the meadow.
habitat
niche
food chain
population
The following organization of levels show the ocean relationships among different organisms related one another in the transfer of energy.
ocean food chain
forest food chain
forest food web
ocean food web
The food web supports which statement?
Organisms are independent from one another.
Each organism has its own, unique food source.
Matter cannot move from one organism to
another.
Matter can be recycled between organisms
and their environment.
In the diagram, which organism provides nutrients for the
largest number of other organisms?
Seal
Herring
Snapper
Bluefish
Which organisms compete for food in the food web to the
right?
Orca and Herring
Seal and Copepod
Killifish and Snapper
Mackerel and Bluefish
Which of these organisms would receive energy from the snake?
Plant
Rabbit
Mouse
Hawk
Which type of consumer could be a first or second consumer?
Herbivore
Omnivore
Carnivore
Producer
If the GRASS became diseased, which organisms would also be NEGATIVELY affected?
Rabbits only
Rabbits and snakes
Rabbits, snakes, and hawks
Rabbits and hawks (snakes benefit)
If the RABBITS became diseased, which organisms would also be NEGATIVELY affected?
Grass and hawks
Grass and snakes
Grass, snakes, and hawks
Snakes and hawks
The 1st law of Thermodynamics
Energy can not be created or destroyed. It just changes forms.
Energy can only be created by the sun
Some energy is lost to the environment.
