This & That, That & This
100
The scientific study of interactions among organisms and between organisms and their physical environment.
What is ecology?
100
Self nourishing.
What is an autotroph or primary producer?
100
The arrows in a food chain illustrate this.
What is the flow of energy through a group on organisms.
100
The biogeochemical cycles of matter involve these three processes.
What are the biological, geological and chemical processes?
100
Ferns. Algae. Not Mushrooms.
What are autotrophs?
200
Temperature, Water, Humidity and Weather
What are abiotic factors?
200
Non-photosynthetic primary producers use these to produce carbohydrates.
What are chemicals?
200
These organisms are always found at the beginning of a food chain or food pyramid.
What are primary producers or autotrophs?
200
Matter moves in this way throughout the biosphere. This is the reason that the statement, "you're made of dinosaurs", is not false.
What is matter is recycled?
200
Oxygen travels in the carbon cycle in this form.
What is carbon dioxide?
300
This level of organization focuses on all the organisms that live in a place, together with their physical environment.
What an ecosystem?
300
Non self nourishing
What is a heterotroph or consumer?
300
Food webs are simply a number of these put together.
What are food chains?
300
Evaporation. Condensation. Precipitation. These components are part of this cycle.
What is the water cycle?
300
This process describes the movement of water molecules into the atmosphere, from plant material (AKA plant sweating).
What is transpiration?
400
These are three way by which ecologist may study an ecosystem.
What is observation, experimentation and modeling?
400
The 6 categories of heterotrophs or consumer.
What are carnivores, herbivores, omnivores, scavengers, detrivores and decomposers?
400
These are the three types of ecological pyramids.
What are pyramids of energy, biomass and numbers?
400
Algae blooms are often the result of excess amounts of this being put into a system.
What is a limiting nutrient?
400
These two processes provide energy for autotrophs.
What is photosynthesis and chemosynthesis?
500
When ecologists produce mathematical formulas designed to predict population fluctuation in a community they use this method of study.
What is modeling?
500
Decomposers are synonymous to this business or center found within many "Green" communities.
What is the recycling center?
500
On average, this percentage of energy is stored in an organism and can be passed on to the next trophic level.
What is 10 %?
500
This process allows atmospheric nitrogen (N2) to be converted to a solid form (ammonia). Bacteria are often responsible for this process.
What is nitrogen fixation?
500
This nutrient is the primary component of fertilizer.
What is nitrogen?
