Question

different species of shark have different types of teeth that can provide clues about what type of food a species of shark commonly eats. what does a shark’s teeth describe about the species of shark in terms of the ecosystem it lives in?
a habitat

b niche

c abiotic factor

d competitive exclusion principle

Explanation:

• Option a: Habitat refers to the physical environment where an organism lives, not directly related to its food - related traits from teeth.
• Option b: A niche includes an organism's role in the ecosystem, such as its feeding habits. Shark teeth, which indicate food type, are part of the shark's niche as they relate to how the shark interacts with its food resources in the ecosystem.
• Option c: Abiotic factors are non - living components of the ecosystem (like temperature, water salinity), and shark teeth are a biological trait, so this is incorrect.
• Option d: The competitive exclusion principle is about two species competing for the same resources, and has nothing to do with what shark teeth indicate about the shark's place in the ecosystem.

Answer:

b. niche
