Answer:

Explanation:

The flatworms are acoelomate organisms that include many free-living and parasitic forms. Most of the flatworms are classified in the superphylum Lophotrochozoa, which also includes the mollusks and annelids. The Platyhelminthes consist of two lineages: the Catenulida and the Rhabditophora. The Catenulida, or “chain worms” is a small clade of just over 100 species. These worms typically reproduce asexually by budding. However, the offspring do not fully detach from the parents and therefore resemble a chain in appearance. All of the remaining flatworms discussed here are part of the Rhabditophora. Many flatworms are parasitic, including important parasites of humans. Flatworms have three embryonic tissue layers that give rise to surfaces that cover tissues (from ectoderm), internal tissues (from mesoderm), and line the digestive system (from endoderm). The epidermal tissue is a single layer cells or a layer of fused cells (syncytium) that covers a layer of circular muscle above a layer of longitudinal muscle. The mesodermal tissues include mesenchymal cells that contain collagen and support secretory cells that secrete mucus and other materials at the surface. The flatworms are acoelomates, so their bodies are solid between the outer surface and the cavity of the digestive system.

Answer:

Mutualism

Explanation:

Organisms in an ecosystem interact with one another from time to time. The close interaction between two organisms is referred to as SYMBIOSIS. Symbiosis is of different types depending on the how it affects the involved organisms. The example in this question depicts MUTUALISM.

Mutualism is the type of symbiotic relationship between two organisms in which both organisms benefit from the relationship. This is the case of the LICHEN, which involves the Algae and Fungi. The algae benefits by making use of the water and minerals supplied by the fungi while the fungi benefits by using the food the algae produces via photosynthesis.
