Question

phloem is a food source for some animals.How can you justify this statement

Answer 1

phloem is the living tissue that transports the soluble organic compounds made during photosynthesis (known as photosynthate), in particular the sugar sucrose,[1] to parts of the plant where needed. This transport process is called translocation.[2] In trees, the phloem is the innermost layer of the bark, hence the name, derived from the Greek word meaning "bark".
justification for food source

Phloem of pine trees has been used in Finland as a substitute food in times of famine and even in good years in the northeast. Supplies of phloem from previous years helped stave off starvation in the great famine of the 1860s. Phloem is dried and milled to flour (pettu in Finnish) and mixed with rye to form a hard dark bread, bark bread. The least appreciated was silkko, a bread made only from buttermilk and pettu without any real rye or cereal flour. Recently, pettu has again become available as a curiosity, and some have made claims of health benefits. However, its food energy content is low relative to rye or other cereals.[citation needed]

Phloem from silver birch has been also used to make flour in the past
