A population of ground-dwelling animals is able to survive on food that is available on the forest floor but receives the best nutrition from fruit found in the canopy of trees. What adaptations will most likely become more common in the population if the availability of the food on the
forest floor decreases? What processes would allow these adaptations to take place?

Answer is in the photo. I can only upload it to a file hosting service. link below!

not sure if this what   you'r looking for would be percent composition

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
