Consider this segment of a food web: snails and grasshoppers eat pepper plants; spiders eat grasshoppers; shrews eat snails and spiders; owls eat shrews. the shrew occupies the trophic level(s) of . primary consumer onlyb. secondary consumer onlyc. tertiary consumer onlyd. primary and secondary consumerse. secondary and tertiary consumers

the correct option is E.

Explanation:

in this case the shrew occupies the level of both secondary and tertiary consumers.

as the shrew eats spider( a secondary consumer) so it is a tertiary consumer but it also eats snails( a primary consumer) so it is therefore a secondary consumer also.

so the shrew occupies both secondary and tertiary consumer trophic level.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
