Ideally, an inventory of an ecosystem should be taken:
before a problem is suspected
chlorophyll
chemical associated with photosynthesis
deciduous forest
chipmunks, black bears, hardwood
The best word to describe a group of microorganisms which float on water is:
community
The complex process of photosynthesis is responsible for:
converting energy to basic food maintaining the food chain supplying energy to man
The biome that would best fit the description of "trees that lose their leaves in autumn" is:
deciduous forest
Which ecosystem is the most resistant to permanent change?
diverse organisms in a large region
What impact does the various energy conversion processes have on ecology?
energy conversion used by man usually produces pollution it is related to natural cycles which affect activities of ecosystem natural energy conversion can help maintain / restore balance
The building blocks of a habitat consists of -blank- factors
environmental
A basic source of pollution is from unnatural sources and people.
false
All the resources of solid waste shown in the pie graph are biodegradable.
false
Pollution caused by pesticides and fertilizers is limited to areas close to the source (farms)
false
photosynthesis
food-making process of green plants and algae
savanna
grass, deer
A whale is found in its natural
habitat
habitat
home for certain kinds of organisms
Ecology is the study of the -blank- between plants and animals.
interrelationships
Large industrial use of wind energy:
is restricted to localized areas of consistent wind
grassland
jack rabbits, foxes, badger
Why is satellite imagery usefull to ecologists?
large-scale regional studies of biomes can be mapped the predominant vegetation of an ecosystem can be monitored natural disasters can be surveyed outstanding environmental factors can be monitored
Which industry produces the largest quantity of solid wastes?
mining
What source of energy provides the majority of energy for the United States?
petroleum
The Earth's food chain starts with:
plants
coniferous forest
porcupines
The sampling technique which employs recording all the organisms within specified square area is called the -blank- technique.
quadrat
inventory
record of organisms /time / area
food chains
sun's energy is passed from plant, to animal, to animal, and so on
What is meant by "solar radiation equilibrium" in related ecology principle?
the complex atmospheric conditions combined with the net influx and radiation outflux produces a long term balance
What is true concerning an ecological community?
the ecosystem of multiple organisms, regardless of a real extent
Concerning the balance of pollutants in the biosphere:
the long term balance of the biosphere under current conditions is uncertain
Biomes are usually named from:
the variety of flora
Natural catastrophes can upset the balance of an ecosystem.
true
Organisms and their nonliving environment are connected.
true
Recycling of garbage, solid wastes and certain crops for generating energy has been accomplished already.
true
Disturbance of the natural environment often produces -blank- results.
unexpected
fresh water aquatic
water lilies, frogs
tundra
wolves, treeless
