postnew [5]

Answer:

light is required to provide energy for photosynthesis

Explanation:

For photosynthesis to take place, it requires the presence of light and chlorophyll. The process has two stages; light and dark stage.

In the light stage, chlorophyll molecules absorb light energy which is used to split water molecules into oxygen and hydrogen atoms. The process is called photolysis.

water→ hydrogen atoms + oxygen.

The hydrogen atoms produced enter the dark stage while oxygen is released in the atmosphere. In the dark stage, carbon dioxide combines with the hydrogen atoms to form simple sugar such as glucose.

A recent study of the marine hawksbill turtle's stomach contents revealed that sponges constitute a major portion of their diet.
bearhunter [10]

Answer:

These structures that protect the sponges from most predators, but not turtles, are spicules.

Explanation:

Sponges <em>skeleton</em> is composed of <em>calcium carbonate and siliceous</em> micro-structures called <u>spicules</u>. Their morphology is so varied that it is used in taxonomy for identification and classification.

There are different kinds of spicules:

-         <em>Monoaxonic spicule</em>: needle-shaped, straights or curves

-         <em>Tetraxonic spicules:</em> they have four prolongations

-         <em>Triaxonic or Hexaxonic spicules</em>

-         <em>Poliaxonic spicules </em>

Two terms can be applied to any of these spicules kinds:

-         <em>Megaspicules</em>: They are elongated and compose the main architecture of the sponge skeleton

-         <em>Microspicules</em>: Variable in shape and size, with ancillary functions

Sponges have few predators thank to the spicule structures and their high toxicity. Many of them are capable of perforating soft tissues and producing urticant substances.
