The shrew occupies the trophic level(s) of _____.a. primary consumer onlyb. secondary consumer onlyc. tertiary consumer onlyd. primary and secondary consumerse. secondary and tertiary consumers

Answer 1

the correct option is E.

Step-by-step 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.
