Answer: Water is drawn in through small openings on a sponge's body called OSTIA.
The supportive skeleton of a sponge contains SPICULES which provide protection from predators.
Explanation:
Sponges refer to any of the aquatic animals of the phyllum porifera which is normally characterized with porous structures and has horn-like calcareous internal framework.
Sponges usually have multiple pores called "OSTIA" on their bodies that allow water to enter them.
Most sponges are sessile and because of this, they can't run away from predators. They usually have sharp "SPICULES" which are part of their skeleton that provide them some certain degree of defense. Apart from this, they also produce toxins which poisons predators that attempt to consume them
There exists the same question from other source that has the table;
The information in the table are as follows:
Ammonia - NH3
Glucose - C8H12O6
Salt - NaCl
Water - H2O
Ammonia, salt and water are alike because, first they are all compounds. They are composed of two different atoms: Ammonia - N and H, Salt - Na and Cl, Water - H and O

The answer is D) desertification and deforestation
To know the answer you can rule out the non-possibilities. A is not correct because farmers use them all the time. B is not correct because water and pesticides can flow downstream and carry and deposit sediment. C is not correct because farmers can flood their own farms. When they plant things and a food comes, all of those plants will die or their roots will detach which lowers the food that can be sold. D is correct because farmers don't farm in the desert or the forest, so it would not be an impact of farming.
