Expert Solution & Answer

Answer to Problem 1TY

Option (d), a species that is in danger of becoming extinct throughout all or a significant portion of its range.

Explanation of Solution

Explanation/justification for the correct answer:

Option (d), a species that is in danger of becoming extinct throughout all or a significant portion of its range. Endangered species are those species that are on the verge of extinction throughout the world. Hence, this option is correct.

Explanation/justification for the incorrect answer:

Option (a), a species that is likely to become extinct in a portion of its range. Endangered species are not the ones whose population is decreasing in the given range but in the whole world. Hence, this option is incorrect.

Option (b), a species that has disappeared in a particular community but is present in other natural environments. Endangered species are not the ones whose population is decreasing in the given range but in the whole world. Hence, this option is incorrect.

Option (c), a species that is extinct. Extinct species are those species whose even one organism is not present on this planet to continue life. While endangered species are those with a limited population. Hence, this option is incorrect.

Option (e) is both b and d. Among the given options, option d is correct. Hence, this option is incorrect.

Conclusion

Among the answers given, a correct answer is an option (d), a species that is in danger of becoming extinct throughout all or a significant portion of its range.

Students have asked these similar questions

Which of the following is not a part of the red list criteria for "critically endangered" species? The population is expected to decline by 25% or more within 3 years or 1 generation. The species has a restricted range <100km2 at a single location and there is observed or predictive habitat loss, fragmentation, ecological imbalance or heavy commercial pollution. Extinction probably is greater than 50% within 10 years or 3 generations. The total population size is less than 200 mature individuals.

Biodiversity is described as: The seasonal and daily changes in an environment The range of different species in an environment The influence of physical factors on an environment The way species differ from one another

The Earth is currently experiencing the sixth mass extinction event. Conservation efforts attempt to identify and focus on the species most at risk of going extinct. Which characteristics make species more vulnerable to extinction? species that have a generalized diet species that have a small population size species that are not negatively affected by introduced species species that are used by humans for food and clothing species that have a long life span
