Food Chains
This is the source of most of the energy on Earth
What is the sun?
This cycle shows how photosynthesis and cellular respiration work together to use carbon over and over again.
What is the carbon cycle?
This term refers to any substance that is added to the environment that cannot be broken down.
What is pollution?
This limiting factor has to do with the amount of space and the amount of food available in an ecosystem.
What is competition for resources?
This term refers to the steady increase int he temperature of Earth's atmosphere.
What is global warming?
This process that plants use, turns sunlight into things like sugar and starch.
What is photosynthesis?
This process in the water cycle is when water is turned into a gas called water vapour.
What is evaporation?
This pollutant, formerly used in paint and packaging materials, is still affecting the Killer Whale population in BC.
What are PCBs?
This tiny limiter uses infections in order to limit a population in an ecosystem. It can affect animals as well as plants.
This model includes the same things in a food chain, but show the number of organisms involved at each level.
What is the pyramid of numbers?
This process is what animals use to turn things like oxygen and food into energy, carbon dioxide, and water.
What is cellular respiration?
This process in the water cycle is when tiny water droplets start forming from the water vapour.
What is condensation?
What are mosquitos?
This line, commonly found on mountains, is easily seen and show exactly where on a mountain that trees cannot grow past.
What is the tree line?
This term refers to the maximum number of individuals in an ecosystem.
What is the carrying capacity?
This green chemical found in plants traps sunlight for processing.
What is chlorophyll?
When organisms die and their carbon is not immediately turned into carbon dioxide, they eventually turn into things like this.
(naming just one is acceptable)
What is coal, oil, and/or natural gas?
This pollutant, which was once common in Canada, killed many birds like the Peregrine Falcon.
What is DDT?
Examples of these limiting factors are avalanches, landslides, forest fires, floods, or extreme weather.
What are Natural Disturbances?
This term, is used instead of food chain because it's more accurate since producers are usually eaten by many different consumers.
What is a food web?
This is the source of energy that can be found at the bottom of the ocean where sunlight does not reach.
What is hydrothermal vents?
This process in the water cycle is when water evaporates from the plants leaves, stem, and flowers.
What is transpiration?
This term refers to the build up of pollutants in an organism.
What is bioaccumulation?
What is predation?
This term refers to the gradual change in the makeup of a biological community over time.
What is ecological succession?
