How do animals help to pollinate flowers
Komok [63]

They are not trying to pollinate the plant. When they move to another flower to feed, some of the pollen can rub off onto this new plant's stigma.

Alenkasestr [34]

Answer:

i have trusted my best to answer

Explanation:

Edit

The upper mantle of Earth is a very thick layer of rock inside the planet, which begins just beneath the crust (at about 10 km (6.2 mi) under the oceans and about 35 km (22 mi) under the continents) and ends at the top of the lower mantle at 670 km (420 mi). Temperatures range from approximately 200 °C (392 °F) at the upper boundary with the crust to approximately 900 °C (1,650 °F) at the boundary with the lower mantle. Upper mantle material which has come up onto the surface is made up of about 55% olivine, 35% pyroxene and 5 to 10% of calcium oxide and aluminum oxide minerals such as plagioclase, spinel, or garnet, depending upon depth.
