Biogeochemical Cycles
This cycle is driven by the sun and the nutrients remain in the same chemical form, only changing states
Water (hydrologic) Cycle
Define the term 'population' for ecology
Populations are the number of organisms of the same species living in a defined space.
What is the term for describing all the things an organism needs and does within its habitat.
the term for finding a balance between Earth’s resources, human needs, and the needs of other species.
Sustainability
A series of predictable stages of growth that a forest goes through is called what?
Ecological Succession
This term is to describe when CO2 released into atmosphere from burning fuel.
Combustion!
We also contribute to the cycle through cellular respiration, consumption, and elimination, but our main negative contribution is through combustion!
Provide an example of a type three species?
(survivorship curve)
Fish, Mosquitos, most plants. (lots of babies, little to no parental care leading to early loss of life in age cohort)
a species that holds the ecosystem together; it is critical for the survival of the other species in the ecosystem
Keystone species
Non-native species introduced to an ecosystem that negatively harms it is called what?
invasive species
Primary Succession starts from bare rock in an area with no previous soil formation. How does this bare rock start to break down?
weathering and species like moss and lichen breaking it down.
The term for the water cycle step where some water seeps underground from the surface of the Earth.
infiltration
Population dispersion is the spatial distribution of organisms in a population. Provide the three categories populations fall in.
Random
Clumped
Uniform/Even
Commonly mistaken as symbiosis, what type of organism interaction produces a win, win relationship where both species benefit.
Mutualism
The term for the normal warming effect when gases trap heat in the atmosphere.
Greenhouse effect
Why would an ecosystem need to go through a secondary round of succession when soil has already been established?
Because of some sort of disturbance (fire/tornado/human land clearing)
through Nitrogen fixing bacteria and lighting strikes!
What is the term for the theoretical maximum population that a given environment could support.
Carrying Capacity
there are 4 types of predation. True predators, parasites, parasitoids and what?
Herbivories (organisms which eat plants for energy)
-CFCs (chlorofluorocarbons) from foam packing material and refrigerant have what key environmental impact?
Burning holes in the Ozone
How do moss and lichen break down solid rock?
they secrete acid to break down the material to get the nutrients from the rock (N/P/S)
What is the chemical difference of Nitrite and Nitrate
Nitrite is NO2- and Nitrate is NO3-
Disease is what type of limiting factor
Density-dependent limiting factors
using common resource at different times, such as wolves & coyotes hunting at different times (night vs. day) is called what?
Temporal Partitioning
the burning of carbon based fuel releases what greenhouse gas?
CO2
What stage of succession has shade tolerant species
Climax community
