1. In the Emission Spectra tool, select each element to see its emission spectrum.

2. In the data table below, record the element symbol, atomic number, the
lowest wavelength present in the spectrum (in nanometers), the highest
wavelength in the spectrum (in nanometers), and the total number of lines in
the spectrum.

3. Watch for any patterns in the spectra. For example, is there any correlation
between an element’s atomic number and the lowest or highest wavelength
in its spectrum? Do larger elements consistently have more spectral lines?

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
