5 examples of amensalism
Answer (1)
Amensalism is a biological interaction where one organism is harmed, and the other is neither harmed nor benefited. 1.) Black walnut tree (Juglans nigra) and other plants: Black walnut trees release juglone, a chemical that inhibits the growth of many plants around them. The walnut tree is unaffected, but other plants are harmed.2.) Penicillin mold (Penicillium) and bacteria: Penicillin mold produces penicillin, an antibiotic that kills many bacteria. The mold is unaffected, but the bacteria are harmed.3.) Large animals and smaller organisms: A large animal, like an elephant, may unintentionally crush smaller plants or insects as it moves through its habitat. The elephant is neither helped nor hurt, but the plants or insects are harmed.4.) Algae blooms and marine life: A large algae bloom can deplete oxygen in the water, creating a "dead zone" where many marine animals cannot survive. The algae are largely unaffected, but the marine life suffers.5.) A large tree shading smaller plants: A large tree can cast a shadow that prevents smaller plants from receiving enough sunlight to grow. The large tree is unaffected, but the smaller plants are harmed.
