less sunlight reaching the ground
B
increased availibility of soil nutrients
C
greater access to water for plants and animals

decreased plant and animal diversity
2) Deer are introduced into a grassland ecosystem and their population increases considerably. If the deer population continues to grow, which is the MOST likely outcome for the ecosystem?
A
Biodiversity would increase, and sustainability would increase.
B
Biodiversity would decrease, and sustainability would decrease.
C
Biodiversity would increase, and sustainability would decrease.
D
Biodiversity would decrease, and sustainability would increase.
3) Which of these is a threat to the survival of an ecosystem?
A
a shrinking variety of animal and plant species
B
predator-prey population cycles
C
competition among some consumer populations
D
less biomass at higher levels of the food web
4) Why is a reduction in biodiversity due to loss of plant populations especially destructive to an ecosystem?
A
Plants are resistant to disease.
B
Plants are part of the food web.
C
Plants have the most biomass.
D
Plants are primary producers.
5) Which of these explains why an ecosystem is healthy when it has a variety of species?
A
An increased number of species allows for fewer food chains.
B
An increased number of species contributes to greater chances for adaptability.
C
A larger number of species reduces competition for abiotic resources.
D
A larger number of species allows for greater diversity in interdependence.
6) Which of these living things in a grassland ecosystem depend on the presence of a variety of bacteria and other microorganisms in the soil?
A
green plants only
B
worms only
C
plants and animals only
D
all the organisms in the ecosystem
7) Which change in the environment would have a negative effect on the survival of a species in an ecosystem?
A
increase in genetic diversity of the species
B
decrease in the population of predators
C
introduction of competing species
D
increase in the population of prey
8) New Zealand is home to many flightless birds, such as the kiwi, which build their nests on the ground. Over time, ground predators such as possums have been introduced. Which statement could be a possible effect on the kiwi?
A
Kiwi could lay three times as many eggs to ensure the survival of their chicks.
B
Possums could eat the eggs and reduce the number of kiwi chicks.
C
Kiwi could develop the ability to fly short distances to escape possums.
D
Possums could make the nests their home so the kiwi have to build new nests.
9) Domesticated rabbits from Europe were brought to Australia. The rabbit population increased so quickly that it caused severe damage to agriculture and the natural environment. Which statement is the BEST conclusion from these events?
A
Humans use technology to help organisms adapt to new areas.
B
Human actions can lead to imbalances in ecosystems.
C
Rabbits from other continents cannot survive in different ecosystems.
D
Rabbit populations decrease when they are placed in new areas.

A
flooding
B
melting glaciers
C
weathering
D
dust storms
11) When hunting by humans causes a species to become extinct, this may produce damaging effects throughout the ecosystem of the extinct species. What is the cause of this damage?

alteration of the food web
C
degredation of habitat
D
modification of climate
12) Toxic chemicals flowing into a stream may also
