what is (a) abiotic and (b) biotic
In general, only about 10% of energy is passed on between trophic levels. This is because some is used by the organism and some is lost as heat.
Water cycle, nitrogen cycle, carbon cycle
What are the 3 types of cycles of our biosphere?
A group of the same organism living in a particular
geographical region.
factors:
➢ influence the density
➢ dispersion
➢ and size of a population.
What is population?
The compound that causes the overheating of the planet?
What is Carbon Dioxide?
Is the close relationship two different species
➢ the anemone provides the clownfish with protection and shelter, while the clownfish provides the anemone nutrients in the form of waste
What is Symbiosis relationships?
Number pyramid
Biomass pyramid
Energy pyramid
what are the types of ecological pyramids measure?
bacteria
What organism drives the nitrogen cycle?
The study of population growth.
What are Demographics?
What compound is depleting our ozone layer
What is Chlorofluorocarbons?
Population
Community
Ecosystem
Biome
Biosphere
what is organization?
The percentage of energy transferred from one trophic level to the next
What is trophic efficiency?
1. Nitrogen fixation
2. Nitrification
3. Assimilation
4. Ammonification
5. Denitrification
What are the 5 main steps of the nitrogen cycle?
Linear (Populations don’t do this!), Logistic (S-shaped), Exponential (J-shaped)
What are the main types of growth?
Excess Nutrients, Algae Bloom, Oxygen Depletion, Dead Zones
What is Eutrophication?
Group of organism that have the ability to reproduce fertile offspring and interbreeding
What is a species?
Energy available equals the amount entering the tropic level, minus total losses from the trophic level.
energy lost as heat + energy lost to detritus
What is calculating available energy?
regulating Earth's global temperature and climate by controlling the amount of carbon dioxide in the atmosphere.
What does the carbon cycle achieve?
The maximum amount of organism an environment can support immensity.
What is Carrying Capacity?
an increase in concentration of a pollutant as you go up the food chain, verses the build up of toxins overtime due to exposure.
What is the difference between Biomagnification and Bioaccumulation?
the location that meets all of an organism's requirements in an environment verse the functional purpose of an organism in an environment
What is the difference between a habitat and a niche?
What is the amount of energy that is transferred between trophic levels?
Begins traveling through the food chain and eventually makes its way into the atmosphere via cellular respiration, burning of fossil fuels, or decay of organisms. While a abundant gas is released to the atmosphere by decay and denitrification and into the ground.
What is the difference between the nitrogen cycle and the carbon cycle?
[Density Dependent] limits or slows population growth because there are too many individuals and [Density Independent] limits or slows population growth regardless of size
What are limiting factors?
DDT [book] awareness and how the affect it has on our limiting factors, such as water and other organisms.
"DDT (dichlorodiphenyltrichloroethane) was applied to control insects that were damaging crops."
What is Rachel Carson book "Silent Spring"?
