The diagram represents a model of a food pyramid in a forest ecosystem.  Which statement best describes what happens in this food pyramid?

• More organisms die at higher levels than at lower levels, resulting in less mass at higher levels.

• Energy is lost to the environment at each level, so less mass can be supported at each higher level.

• When organisms die at higher levels, their remains sink to lower levels, increasing the mass of lower levels.

• Organisms decay at each level, and thus less mass can be supported at higher levels

Fossils of tropical plants and animals have been discovered in regions now known for their icy conditions, such as Antarctica. What does this indicate about the historical climate of these regions before they reached their current positions?

• These regions were colder before they shifted to their current locations

• These regions were warmer before they shifted to their current locations

• The organisms migrated to these regions after they shifted

• These fossils were artificially placed there
