Answer:

The answer is:

B. Worms consuming the blood from mammals.

Algae isn't causing any harm to the sloth, rather its providing it with camouflage to hide from predators. Both creatures benefits since the algae gets to eat any parasites and other things in the sloths fur, plus they get a free ride and home in the process. The sloth isn't harmed and is helped by the algae since it provides camouflage (mutualism).

Tree frogs aren't causing harm to the trees since they are only using them to hide from predators, the tree serves as protection for the frogs and aren't harmed in the process (commensalism).

Two fish protecting each other from predators aren't harming each other in any way, rather they are protecting each other from another animal that wants to eat them (mutualism).

The worms however are harming the mammals because they are consuming the mammals blood, this is parasitism since one animal is benefiting and the other is harmed.

Hope this helps! :)

It consist of sieve elements, which are the conducting vessel that aids transport of sugar round the body. They are very active before maturity at mature they are no longer in use.

Companion cells are used in replacement of sieve element at maturity, they function in metabolism together with the sieve tube Translocation is the transport or movement of sugar round the body.

Girdlings is the removal of the bark of a plant this can inhibit active transport of food.

Non-reducing sugar are monosacharrides such as glucose that are produce and transported round the body of the plant.

P-protein are found in the plants sap usually in large amount in the sieve elements.
