Read the following statements (1 - 4) related to competition and select the correct option stating true (T) and false (F)

• A. 1 - T, 2 - F, 3 - T, 4 - F
• B. 1 - T, 2 - F, 3 - F, 4 - T
• C. 1 - F, 2 - F, 3 - T, 4 - T
• D. 1 - F, 2 - T, 3 - F, 4 - T

Answer 1

The correct option is B 1 - T, 2 - F, 3 - F, 4 - T

Competition is a type of population interaction in which the fitness of one species is significantly lower in the presence of another species.

Competition between individuals of the same species is called intraspecific competition.

Hence, statement 3 is incorrect.

Competition between individuals of different but closely related species competing for same resources that are limited is called interspecific competition.

Hence, statement 4 is correct.

In the Galapagos islands, the Abingdon tortoise became extinct within a decade after the introduction of goats. The probable reason for this is the greater browsing efficiency of the goats.

Hence, statement 2 is incorrect.

The ‘Competitive Exclusion Principle’ was proposed by Georgy Guase, a Russian biologist.

It states that two closely related species competing for the same resources cannot coexist indefinitely and the competitively inferior one will be eliminated eventually.

Hence, statement 1 is correct.
