Answer:
Tiltmeters and strainmeters measure subtle changes in ground slope and shape at volcanoes. .
Explanation:
Measuring tiny changes in the slope angle or "tilt" of the ground and the shape or "strain" in the earth's crust are time-tested methods for monitoring volcano deformation caused by moving magma.
The species was a keystone species.
Keystone species are the species that ''hold the ecosystem together''.
They have an important role in the trophic networks (food chains) and often they can even afflict changes in the abiotic part of the ecosystem (change the composition of soil, purify the water, lower the effect of the wind etc)
Therefore, when a keystone species is removed it affects greatly the whole ecosystem.
