Briefly explain how energy is transferred from organism to organism in the food web.

energy is transferred between trophic levels when one organism eats another and gets the energy-rich molecules from it's prey body.

Explanation:

however these transfers are inefficient,and this inefficiency limits the length of food chains

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.  

since there are no options posted i'll give you a few examples.

a dolphin's flipper, bird's wing, cat's leg.
