Answer:
A snail eats a clam.
Explanation:
Interactions always occur between organisms in an ecosystem. An interaction between two organisms is called SYMBIOSIS. Symbiosis consists other types which includes PREDATION. Predation is a kind of symbiotic relationship between two organisms in which one kills and feeds on the other in order to obtain energy. The organism that kills is called the PREDATOR while the organism that is killed is called PREY.
In this example, a snail feeding on a clam best represents the example because the snail (PREDATOR) is obtaining energy by killing the clam (PREY). In other options, no organism is killed.

The correct answers are "ciprofloxacin is an antibiotic", "albuterol is a bronchodilator", and "prednisone is a corticosteroid". Ciprofloxacin is an antibiotic in the class of fluoroquinolones, effective against respiratory infections since patients with COPD has mucus hypersecretion which predisposes the patient to respiratory infections. Other antibiotics include respiratory fluoroquinolones such as levofloxacin and moxifloxacin, cephalosporins such as cefuroxime and ceftriaxone, and beta-lactams such as co-amoxiclav. Albuterol is a short acting beta-agonist (SABA) which actions as a bronchodilator by relaxing bronchial smooth muscles. Other popular SABA is salbutamol. Prednisone is a corticosteroid which actions to prevent inflammation by blocking the arachidonic acid pathway and therefore block the formation of inflammatory mediators.
Decadron is dexamethasone which is a steroid. Bactrim is TMP/SMX which is an antibiotic.
