White-breasted nuthatches and downy woodpeckers both eat insects that hide in the furrows of bark in hardwood trees. the downy woodpecker searches for insects by hunting from the bottom of the tree trunk toward the top, whereas the white-breasted nuthatch searches from the top of the trunk down. these hunting behaviors best illustrate which of the following ecological concepts?
1. character displacement2. asymmetric competition3. resource partitioning4.spatial divergence

scientific laws are the result of testing theories and proving them to be facts.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
