natali 33 [55]

Answer:

Fungi indirectly help the fishes by providing digested organic nutrients to their prey insects.

Explanation:

According to the given information, fishes are predators of insects. These insects feed on dead leaves. The insects are not able to digest the cellulose of dead leaves. Fungi breakdown the dead and decaying leaves and digest the complex molecules such as cellulose into simpler organic nutrients which in turn are consumed by insects.

If fungi do not decompose the dead leaves, insects would not be able to derive the organic nutrients from them. A shortage of food supply to insects would starve them. Unavailability of prey insects would starve fishes. Thereby, fungi indirectly benefit the fishes to obtain their nutrition from the insect.

Diano4ka-milaya [45]

Answer:

The answer is False. Although sensitive cells are <u>more abundant</u> in the <u>anterior portion</u> of the annelid´s body, in general, they are arranged in all the segments.

Explanation:

Annelids, such as the earthworm, have a variety of sensory cells:    

  • <u>Mechanoreceptors</u>, disposed of in groups in <em><u>each segment</u></em> of their body.  
  • <u>Photoreceptors</u>: Light-sensitive cells. Although they are <em><u>located in the whole </u></em>body, they are <em><u>abundant in anterior and posterior segments</u></em>, concentrated in the intern and dorsal part of the epidermis.
  • <u>Humidity receptors</u> are the most sensitive cells and are <u>located in the first segments</u> of the earthworm body
  • <u>Chemoreceptors</u>: sensorial cells cumulus forming a prominent tubercle with prolongations that extends through the cuticle. These tubercles form three rings <em><u>in each segment</u></em> but are especially <em><u>abundant in the anterior part</u></em> of the body.

The tegument is very rich in free nervous terminations, which functions might be tactile.
