After part of a wetland was drained, frog breeding pools dropped from 18 to 4, and counted tadpoles dropped from 900 to 120. What claim is supported?
After a fire cleared understory shrubs, shrub cover fell from 70% to 20%, and ground-nesting sparrow nests fell from 45 to 12. What claim is supported?
During a drought, a pond's average depth fell from 2.0 m to 0.5 m, and minnow counts fell from 500 to 160. What claim is supported?
After invasive mussels appeared on stream rocks, native clam density fell from 40 per m² to 8 per m². What claim is supported?
After insecticide was sprayed along field edges, insect counts fell by 80%, and swallow fledglings fell from 60 to 22. What claim is supported?
When streamside trees were removed, midday water temperature rose from 14 °C to 22 °C, and trout counts fell from 86 to 30. What claim is supported?
After sea stars were removed from tide pools, mussel cover rose from 20% to 80%, and algae species fell from 8 to 3. What claim is supported?
A student argues that road salt runoff reduced salamander populations in ponds. What evidence would best support this argument?
A class argues that removing wolves changed forest populations by increasing deer and reducing young trees. What evidence would best support this argument?
A student argues that drought reduced a bee population by reducing flowers. What evidence would best support this argument?
A student argues that fertilizer runoff caused fish deaths in a lake. What evidence would best support this ecosystem argument?
A team argues that coral bleaching reduced reef fish populations. What evidence would best support this claim?
A student argues that an invasive vine reduced native bird nesting in shrubs. What evidence would best support this argument?

A disease killed many oak trees. The squirrel population fell the next year. What reasoning best connects this change to squirrel numbers?
An invasive grass made fires more frequent. Native shrubs declined, and quail counts fell. What reasoning best links the change to quail?
Mosquito fish were added to a pond and ate many tadpoles. Adult frog counts fell later. What reasoning best links the evidence?
