Answers
1
The organisms in a pond and the physical factors influencing them best describe
a food chain
a population
an ecosystem
a biosphere
2
The carrying capacity for herbivores in a habitat is most affected by the availability of
carbon dioxide in the atmosphere
heat energy released by carnivores
decomposers in the soil
photosynthetic organisms
3
The flow of energy in an ecosystem is best described as energy moving in
one direction from a consumer to a producer
two directions between the producers that are present
two directions, back and forth, between the producers
one way from the Sun to the plants and then to the consumers
4
The stability of the rabbit population size is most likely the result of
the development of mutations in young rabbits
rabbits continuing to reproduce when the population is large
the survival of more female rabbits than male rabbits
environmental factors that keep the population in check
5
Which best describes the flow of energy and the movement of chemical compounds in an ecosystem?
Energy is transferred from organism to organism in a web.
Energy flows into living organisms and remains there
Chemical compounds flow in one direction
Energy flows out of living organisms and is lost
6
One advantage of biodiversity in an ecosystem is that it
guarantees that the largest organisms will dominate the area
ups the chance that some organisms will survive major change
develops relationships btwn organisms and always positive
ensures a large amount of identical genetic material
7
Why is a mushroom considered a heterotroph?
It divides by mitosis.
It manufactures its own food.
It transforms light energy into chemical energy.
It obtains nutrients from its environment.
8
The diversity of ecosystems is most likely the result of
increased efforts to protect endangered species
a lack of competition between the heterotrophs living there
the variety of abiotic conditions in these regions
interactions between producers and decomposers
9
Small bushes replace the grasses, which in turn are replaced by trees. This is...
stability
succession
coordination
cultivation
10
If manatees became extinct, what would be the most likely result?
Other manatees would move into these areas
The biodiversity of these areas would not be affected.
Predators in these areas would occupy higher levels
Certain producer organisms would become more abundant
11
Which organisms are carnivores?
frog, snake, and hawk
deer and mountain lion
grass and trees
mouse, rabbit, and cricket
12
A
decrease
in the grass population will most immediately decrease the available energy for the
mouse
snake
hawk
frog
13
Based on the information provided in the graph, the process that is occurring is
selective breeding
genetic engineering
biological evolution
ecological succession
14
Which type of organism can get energy directly from any of the other organisms in an ecosystem?
decomposer
producer
herbivore
carnivore
15
Deer ticks feed on the blood of organisms like mice, deer, and humans, is best described as a
scavenger
predator
parasite
host
16
Abiotic factors that affect the growth of grass in a lawn include
moisture and minerals
bacteria and soil
Soil and plants
earthworms and nutrients
17
Decomposers are necessary in a food chain because they
absorb energy from the Sun
manufacture food by photosynthesis
produce organic nutrients
return nutrients to the ecosystem
18
Two species of similar animals do not compete for food. This is because they most likely
occupy different ecological niches
are the same size
reproduce at different times of the year
are active at night
