Science Regents Practice Review Test.

3) Certain herbivores will exceed carrying capacity - CORRECT ANSWER If humans remove carnivorous
predators such as wolves and coyotes from an ecosystem, what will probably be the first observable
result ?



1) The natural prey will die off

2) Certain plant population will increase

3) Certain herbivores will exceed carrying capacity

4) The decomposers will fill the predator niche



1) ecosystem - CORRECT ANSWER Which ecological term includes everything represented in the
illustration below ?

1) ecosystem

2) community

3) population

4) species



2) significant changes occur in the ecosystem - CORRECT ANSWER In an ecosystem, the presence of
many different species is critical for the survival of some forms of life when

1) ecosystems remain stable over long periods of time

2) significant changes occur in the ecosystem

3) natural selection does not occur

4) the finite resources of Earth increase



1) convert large molecules into simpler molecules that can then be recycled - CORRECT ANSWER
Decomposers are important in the environment because they

1) convert large molecules into simpler molecules that can then be recycled

2) release heat from large molecules so that the heat can be recycled through the ecosystem

,3) can take in carbon dioxide and convert it into oxygen

4) convert molecules of dead organisms into permanent biotic parts of an ecosystem



3) carnivores - CORRECT ANSWER Which ecological term best describes the polar bears in the cartoon ?

1) herbivores

2) parasites

3) carnivores

4) producers



2) a good conservation practice for renewable natural resources - CORRECT ANSWER In some areas,
foresters plant one tree for every tree they cut. This activity is an example of



1) lack of management of nonrenewable natural resources

2) a good conservation practice for renewable natural resources

3) a good conservation practice for nonrenewable natural resources

4) lack of concern for renewable natural resources



1) energy released into the environment as heat - CORRECT ANSWER A food chain is represented the
curly arrow represented most likely indicates

1) energy released into the environment as heat

2) oxygen produced by respiration

3) the absorption of energy that has been synthesized

4) the transport of glucose away from the organism



2) carrying capacity - CORRECT ANSWER An environment can support only as many organisms as the
available energy, minerals, and oxygen will allow. Which term is best described by this statement ?



1) biological feedback

2) carrying capacity

3) homeostatic control

, 4) biological diversity



4) increasing populations of native fish that feed on mosquito larvae in the swamps - CORRECT ANSWER
Communities have attempted to control the size of mosquito populations to prevent the spread of
certain diseases such as malaria and encephalitis. Which control method is most likely to cause the least
ecological damage ?



1) draining the swamps where mosquitoes breed

2) spraying swamps with chemical pesticides to kill mosquitoes

3) spraying oil over swamps to suffocate mosquito larvae

4) increasing populations of native fish that feed on mosquito larvae in the swamps



1) the trade- offs involved - CORRECT ANSWER In an attempt to improve environmental quality, local
officials in a country in New York State want to build a garbage-to-steam plant. At the plant, garbage
would be burned to produce energy, but air pollution would also be produced. In order to decide
whether or not to build this plant, the community must consider



1) the trade- offs involved

2) new genetic technology

3) the natural process of succession

4) energy flow between organisms



1) the same habitat, but different niches - CORRECT ANSWER In a forest community, a shelf fungus slug
live on the side of a decaying tree The fungus digests and absorbs materials from the tree, while the slug
eats algae growing on the outside of the truck. These organisms do not compete with one another
because they occupy



1) the same habitat, but different niches

2) the same niche, but different habitats

3) the same niche, and the same habitat

4) different habitats and different niches
