Where do producers receive its energy?

the sun

Explanation:

Producers tend to be plants and usually act as the base for a food chain/pyramid. Using this plus knowledge about plants and photosynthesis, (the process that plants use to make food/get energy) we can come to the conclusion that producers (plants) get their energy from the sun (using photosynthesis).

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.
