AICE ENVIRONMENTAL MANAGEMENT
QUESTIONS AND ANSWERS SET A+
✔✔Transpiration - ✔✔Evaporation of water from the leaves of a plant
✔✔main gasses of the atmosphere - ✔✔nitrogen • oxygen • carbon dioxide • argon •
water vapour
✔✔What layer contains ozone - ✔✔Stratosphere
✔✔function of ozone layer - ✔✔Keeps most UV light from reaching Earth
✔✔Atmospheric layer where weather occurs - ✔✔Troposphere
✔✔Explain the greenhouse effect and its role in maintaining Earth's temperature. - ✔✔•
ultraviolet radiation (shortwave radiation) passes through the Earth's atmosphere and is
absorbed by the Earth's surface • some energy is re-emitted back into the atmosphere
as infrared radiation (longwave radiation) • greenhouse gases absorb some of this
infrared radiation and prevent it from leaving the atmosphere
✔✔Biome - ✔✔A group of ecosystems that share similar climates and typical organisms
✔✔Ecosystem - ✔✔A biological community of interacting organisms and their physical
environment.
✔✔Population - ✔✔A group of individuals that belong to the same species and live in
the same area
✔✔Community - ✔✔All the different populations that live together in an area
✔✔habitat - ✔✔Place where an organism lives
,✔✔Niche - ✔✔Full range of physical and biological conditions in which an organism
lives and the way in which the organism uses those conditions
✔✔Abiotic Factors - ✔✔Nonliving components of environment.
✔✔biotic factors - ✔✔living and once living parts of an ecosystem
✔✔List the (3) types of biotic factors - ✔✔Producers, Consumers (primary, secondary,
tertiary), Decomposers
✔✔List the (7) abiotic factors of an ecosystem - ✔✔Temperature - Humidity - Water -
Oxygen - Salinity - Light - pH
✔✔Producers - ✔✔Organisms that make their own food using the sun
✔✔Consumers - ✔✔An organism that obtains energy and nutrients by feeding on other
organisms or their remains.
✔✔decomposers/detritivores - ✔✔An organism that breaks down wastes and dead
organisms
✔✔primary consumers (herbivores) eat - ✔✔producers
✔✔secondary consumer - ✔✔An organism that eats primary consumers
✔✔tertiary consumers (carnivores) - ✔✔organisms in the fourth trophic level (eg, hawks
and sea otters), which obtain their energy by eating secondary consumers
✔✔Describe how biotic factors affect the number and the diversity of organisms found
within an ecosystem - ✔✔Biotic factors impact the availability of food sources to
secondary and tertiary consumers. They impact the populations of herbivores and
producers. The more diversity in the ecosystem the more resilient it is to change.
✔✔Interspecific competition - ✔✔competition between members of different species
✔✔intraspecific competition - ✔✔competition between members of the same species
✔✔grazing - ✔✔act of feeding on plants
✔✔Predation - ✔✔An interaction in which one organism kills another for food.
✔✔photosynthesis - ✔✔the process by which green plants and some other organisms
use sunlight to synthesize glucose from carbon dioxide and water.
, ✔✔Formula for photosynthesis - ✔✔6H₂O + 6CO₂ + Light Energy → C₆H₁₂O₆+ 6O₂
✔✔pigment in the plant that captures light for photosynthesis - ✔✔Chlorophyll
✔✔4 factors that affect photosynthesis - ✔✔temperature, light intensity, amount of
carbon dioxide and the availability of water.
✔✔Carbon stores - ✔✔Places where carbon accumulates for a period of time such as
rocks, oceans, atmosphere and plant matter.
✔✔trophic level - ✔✔Each step in a food chain or food web
✔✔food chain - ✔✔A series of steps in which organisms transfer energy by eating and
being eaten
✔✔food web - ✔✔a system of interlocking and interdependent food chains.
✔✔What is transferred between organisms on a food chain/web - ✔✔energy
✔✔energy pyramid - ✔✔A diagram that shows the amount of energy that moves from
one feeding level to another in a food web
✔✔pyramid of biomass - ✔✔A pyramid that illustrates the total mass of all the
organisms in a trophic level.
✔✔pyramid of numbers - ✔✔representation of the number of individual organisms in
each trophic level of an ecosystem
✔✔aerobic respiration - ✔✔Breaking down glucose in the presence of oxygen to create
energy and carbon dioxide
✔✔Formula for aerobic respiration - ✔✔C6H12O6 + 6O2 --> 6CO2 + 6H20 + energy
✔✔word formula for photosynthesis - ✔✔Carbon Dioxide + Water ------Sun------>
Glucose + Oxygen
✔✔word formula for cellular respiration - ✔✔oxygen + glucose > carbon dioxide + water
+ energy
✔✔Carbon Cycle Steps - ✔✔1. Carbon enters the atmosphere as carbon dioxide from
respiration and combustion. 2. Carbon dioxide is absorbed by producers to make
carbohydrates in photosynthesis. 3. Animals feed on the plant passing the carbon
compounds along the food chain. Most of the carbon they consume is exhaled as
carbon dioxide formed during respiration. The animals and plants eventually die. 4. The
