Lesson 1 & 2
The definition of ecosystems.
What is a group of organisms that interact with each other in a certain environment?
Examples of fossil fuels.
What is oil, gas and coal?
What is an organism consuming another?
What do we call an ecosystem when photosynthesis and cellular respiration are balanced, abiotic conditions are stable, energy is flowing through the ecosystem, things can be stable.
What is equilibrium?
The definition of ecological succession.
What is the growth of an ecosystem toward a climax community/stable ecosystem?
Define chemical control of an invasive species.
What is the use of pesticides or other chemicals to control the growth rate of a species or eliminate it.
The chemical process of photosynthesis (formula).
What is H2O + CO2 _->_sunlight_->_ C6H12O6 + O2
The difference between bioamplification and bioaccumulation.
What is the accumulation of a pesticide within an individual organism vs. the process of passing pesticides through a food chain and increasing as you get higher up in the food chain.
What determines the carrying capacity of a certain population.
What are limiting factors ie., predators, abiotic or other biotic factors.
What happens during primary succession.
What is the growth/development of an ecosystem from from a barren landscape/bare rock?
Explain at what trophic levels you find producers and primary consumers.
What is first trophic level for producers and second trophic level for primary consumers.
How is acid rain produced?
What is SO2 and nitrogen oxide compounds that leave the Earth through vehicle emissions or burning fossil fuels. They mix with the moisture in the atmosphere and fall back down to Earth with a LOWER pH than normal rain.
The definition of mutualism, commensalism and parasitism?
What is a relationship that benefits both organisms? What is a relationship that benefits one organism but doesn't affect the other? What is a relationship that benefits one organism and harms the other?
Where is the most energy found in an energy pyramid?
What is in the producers at the bottom. 10% of the energy in an organism that is passed down to the next?
What happens during secondary succession.
What is the growth/development of an ecosystem that happens after some king of disturbance (forest fire)?
The importance of biodiversity and what it refers to.
What makes ecosystems sustainable and resilient? What refers to having many different populations that can fill a certain niche?
The reserves of Carbon.
What is the atmosphere, fossil fuels and oceans?
The definition of competition.
What is it when 2 organisms compete for the same resource like food, space and mates?
What consumes dead/decaying material and breaks it down internally vs. what breaks down material using enzymes externally & absorbs the nutrients?
The type of species where succession can begin.
What is a pioneer species (eg. lichens)?
What causes access algae bloom growth in aquatic ecosystems?
What is the spring runoff from nitrogen in fertilizers?
Where does photosynthesis occur?
Where is the chloroplast of plant cells and in autotrophs?
What are some economic impacts of acid rain? (2)
What is the loss of wood from damaged forests, Reduction in fish stocks and ruining recreational, fishing industry, Damages steel structures, limestone buildings and stone monuments.
Look at this food web. Make a food chain out of the web.
What is...
What is an ecosystem where humans maintain the abiotic and biotic factors intensively ie., a farm for human agriculture benefit and production. What is where one species of an organism is grown.
