In the energy pyramid for any given ecosystem, the most energy available is at the bottom and the least energy available is at the top.
At the bottom of the energy pyramid are the producers (plants and other photosynthetic organisms). The first group of organisms that consume the producers are called the primary consumers (herbivores). The next group of consumers are the secondary consumers, and then the tertiary consumers and quaternary consumers.

Answer:
carries food produced by leaves
Explanation:
The diagram is a cross section of stem of a dicot plant, specifically <em>Hypericum perforatum</em>. It shows all the structures present in the stem like xylem, phloem, pith, cortex etc. The structure labelled X is phloem. It is present between xylem (stained red) and peripheral cortex. Phloem is responsible for conduction of sugars and nutrients in the plant thus it carries the food produced by leaves. Together xylem and phloem make the vascular tissue which surrounds the central pith (stained bluish-green).
