The graph shows the change in the dates for the onset of caribou calving 20 points
season and the plant growing season in the Arctic over an eight-year
period. Based on the graph, what do you think scientists have discovered
about the relationship between the plants and caribou?A graph with its
horizontal axis labeled "Year" from 2001 to 2009 in intervals of 2 and its
vertical axis labeled "Date" from Early Spring to Late Spring. Over the
years from 2001 to 2009, Plant growing season moves from Late Spring
to Early Spring. Over the years from 2001 to 2009. Caribou calving
season moves from higher Late Spring to lower Late Spring. Based on the
graph, what do you think scientists have discovered about the plants and
caribou?

The plant growing season and the caribou calving season respond the same way to
the increase in early spring temperatures.
The caribou calving season and the plant growing season are both determined by
seasonal changes in the length of day.
More calves survive because they no longer have to compete with the plants for
resources
O
The caribou calving season is affected by the availability of plants to eat.
