How does photosynthesis affect the flow of energy in the biosphere

The flow of energy is determined by the process which is known as photosynthesis. This is because only producers have the capability to make food.

The food from the plants are transferred to the animals, primary consumers. The food from the primary consumers are transferred to the secondary consumers.

From there it gets transferred to the tertiary consumers. This is how photosynthesis maintains the flow of energy in an ecosystem.

what's the

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.
