Ecosystems & Succession
The scientific study of interactions among organisms with each other and with the environment
What is ecology
These kinds of ecological systems (including the water cycle, nitrogen cycle, and carbon cycle) are so named because they describe cycles of LIFE, EARTH, and ELEMENTS.
What are BioGeoChemical Cycles?
This is one example of a resource for which different species compete.
What is food? water? shelter? mates? nesting sites? sunlight? soil?
This biome is typically a flat and treeless region of land that has a layer of permafrost
What is a tundra?
These consumers will consume both plants AND animals for energy.
What are omnivores?
These kinds of nonliving factors can and do affect ecosystems: soil, climate, pollution.
What are Abiotic factors?
This is one type of fossil fuel, which takes millions of years to form from the decayed remains of ancient organisms.
What is natural gas? coal? oil?
A symbiotic relationship in which one individual is harmed but the other is benefitted.
What is parasitism?
Chicago is located around one of these two biomes (name one)
What is grassland?
What is temperate forest?
Unlike producers (or autotrophs) this category of organisms get their energy by consuming other organisms.
What are consumers?
What are heterotrophs?
This describes the relationship between living organisms and their environment. Every organism relies on other organisms to survive.
What is interdependence?
What is photosynthesis?
A symbiotic relationship in which both participating individuals benefit
What is mutualism?
What is an estuary?
This is the approximate percentage of energy that is passed from one trophic level to the next.
What is 10 percent?
Within an ecosystem, the variety of organisms, their genetic differences, and where these differences occur.
What is biodiversity?
This phenomena is part of the Water Cycle, by which water evaporates directly from plants
What is transpiration?
Species that are brought to a new habitat by human means (may be purposeful or accidental, e.g., tourism, travel)
What are invasive species?
This is one of many actions I can take to reduce my carbon footprint.
TA choice.
These organisms are important parts of many geochemical cycles: they cause decay and release nutrients back into the environment. Some examples include mushrooms or bacteria.
What are decomposers?
On land, this type of succession occurs where no soil previously existed
What is primary succession?
This necessary element makes up over 70% of our atmosphere, but most organisms are unable to use it in this form--we rely on bacteria in the soil to fix it into compounds usable by other living things
What is Nitrogen?
A symbiotic relationship in which only one individual benefits, but the other remains unharmed.
What is commensalism?
We can and should pressure our elected officials to protect our state and national parks, because trees are a critical part of this biogeochemical cycle.
What is the water cycle?
What is the carbon cycle?
In the following food chain: leaf--> grasshopper--> frog--> snake--> owl, this term describes what type of consumer is the frog.
What is secondary consumer?
