Question

many tropical ferns live on other plants without withdrawing nutrients from them. these ferns are said to be

epiphytes

bryophytes

parasites

pathogens

saprophytes

question 16 (2.5 points)

which plants are widely planted in cities because of their resistance to air pollution?

lycopods

ginkgos

Explanation:

• Epiphytes: These are plants that grow on other plants (like trees) but do not take nutrients from them. They get nutrients from the air, rain, and debris around them. This matches the description of the tropical ferns in the question.
• Bryophytes: These are non - vascular plants like mosses. They do not grow on other plants in the way described.
• Parasites: Parasitic plants take nutrients from the host plant, which is not the case here.
• Pathogens: These are disease - causing organisms (not just plants) and do not match the description.
• Saprophytes: These are organisms that feed on dead and decaying matter, not living plants.

For the second question:

• Lycopods: These are club - mosses and are not typically known for air - pollution resistance.
• Ginkgos: Ginkgo trees are known for their resistance to air pollution. They can tolerate pollutants like ozone, sulfur dioxide, and carbon monoxide better than many other tree species.

Answer:

Question 15: epiphytes
Question 16: ginkgos
