Human Impacts on Ecosystems
100
Living things in the environment such as:
- Animals
- Plants
- Fungi
- Bacteria
Biotic
100
These organisms produce food energy for themselves and all other organisms on Earth
Use energy from the Sun (photosynthesis) and nutrients in the soil/water to grow
Producers
100
Accidental or planned introduction of a non-native species into a community.
Bioinvasion
100
When a liquid changes into vapour.
Evaporation
100
When a species no longer exists anywhere on earth
Extinct
200
Non-living things in the environment such as:
- Air
- Water
- Soil
- Sunlight
- Minerals and Nutrients
Abiotic
200
These organisms eat other living things:
- they eat the food made by producers, directly or indirectly
Consumer
200
More than one living thing trying to reach the same goal
Competition
200
When water that is taken up through a plant’s roots evaporates from its leaves, stem, and flowers.
Transpiration
200
Organisms that are so rare that they are in danger of becoming extinct
Endangered
300
What are the 4 basic needs of living things?
Food, water, suitable habitat, exchange of gases.
300
These are the 3 types of consumers.
- Herbivore
- Omnivore
- Carnivore
300
Animals getting their food by killing and eating other organisms
Predation
300
When vapour changes into a liquid. Warm air contains water vapour, which condenses into clouds, fog, or dew.
Condensation
300
Species whose numbers are declining
Threatened
400
White fur in snowy areas, camouflage, webbed feet or flippers to swim fast, long beaks for getting insects are all examples of this inherited characteristic that helps an organism survive in its environment.
Adaptation
400
Organisms that get matter and energy they need from wastes and dead plants and animals
Decomposers & Scavangers
400
Two types of weather that can affect an ecosystem
Poor Conditions and Natural Disasters
400
When water vapour that forms from the condensation inside of clouds falls as rain, sleet, snow, or hail.
Precipitation
400
1950’s - Malaria carrying mosquitoes infected people in Borneo
The solution?
DDT - Chemical Pesticide
500
A symbiotic relationship between two different organisms in which both benefit.
Mutualism
500
Movement of pollutant through the levels of a food chain so that greater quantities are present up the food chain.
Bioaccumulation
500
What type of consumer would the FOX be:
Secondary
500
Identify one of the processes in this carbon cycle that releases carbon into the atmosphere
- Burning fossil fuels
- animal decay
- respiration
- forest fires
500
Affected small bugs eaten by geckos. Geckos suffered nerve damage and moved more slowly. Cats started hunted slow moving geckos instead of rats and died from DDT poisoning. Rat population increased and so did the diseases they carry.
An example of:
An example of the Negative Effects of DDT
600
A symbiotic relationship where one organism benefits and the other partner neither loses or gains (neutral).
Commensalism
600
This organism has the largest population in this food pyramid:
Trees and vegetation.
600
The approximate percentage of food energy stored available to be eaten/consumed
10%
600
The cycle shown in this diagram.
The water cycle
600
Dawson's Caribou, Sea Mink, Great Auk, Labrador Duck are all:
Extinct
700
A symbiotic relationship where one organism benefits and the other is harmed.
Parasitism
700
This organism has the lowest population in this food pyramid:
Lion
700
A calculation of the total area of land and water needed to supply all of the materials and energy that you use, as well as the waste that you produce
Includes food, water, supplies to build shelters and make all the things you use
Includes energy (electricity, natural gas etc.) required to run, manufacture, and transport all the things that you buy
Ecological footprint
700
This type of precipitation has a pH value below 5.6 because sulfur and nitrogen pollutants reacted with water vapour in the atmosphere.
Acid rain
700
Describe a way humans can impact or change an ecosystem.
Be specific
