Is cypris autotrophic or heterotrophic

Cypris is a heterotroph.

Explanation:

Cypris are the members of kingdom Animalia which are multicellular crustaceans. These organisms are both marine and fresh water, but most of them are fresh water pond dwellers. They are microscopic, which needs to be seen through microscope at 40x for proper visualization.

Cypris are heterotrophs which live in the debris below the water bodies and collect their food from them only. They are covered by 2 shells, and a pair of antennae and limbs project out of the body. They are easily eaten by hydra and small fishes as delicious food.

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.
