Question

300 million years ago, during the carboniferous period, millipedes grew up to 200 centimeters (cm) long. table 1 shows the lengths of modern and carboniferous millipedes. table 1. millipede sizes

	length (cm)
carboniferous millipedes	30 - 200	during the carboniferous period, there were vast swamps near the equator. these swamps were very wet land - based ecosystems, where a large number of plants lived. due to the high number of plants in a given area, plant material was quickly covered by other plant material when they died. over geologic time, this plant material became coal. part a which conclusion can be made based on table 1 and figure 2? a the size of millipedes increased as carbon dioxide in the atmosphere decreased. b the size of millipedes decreased as carbon dioxide in the atmosphere decreased. c the size of millipedes remained unchanged as carbon dioxide in the atmosphere decreased. d the size of millipedes first increased, then decreased, as carbon dioxide in the atmosphere decreased. part b

Explanation:

Se observa que los milpièdes del período Carbonífero (tamaño de 30 - 200 cm) son en promedio más grandes que los milpièdes modernos (tamaño de 11 - 38 cm). El período Carbonífero tuvo una atmósfera con más dióxido de carbono en comparación con la atmósfera actual. Por lo tanto, se puede concluir que el tamaño de los milpièdes disminuyó a medida que el dióxido de carbono en la atmósfera disminuyó.

Answer:

B. The size of millipedes decreased as carbon dioxide in the atmosphere decreased.
