Question

The population growth of a plant species can be influenced by which of the following factors?

I. Intraspecies competition

II. Predation

III. Nutrient availability

• A. I only
• B. II only
• C. III only
• D. I, II and III
• E. II and III

Answer 1

The correct option is D I, II and III

Intraspecific competition is an interaction where members of the same species compete for limited resources. This leads to a reduction in fitness for both individuals.

Nutrient availability in the given area affects the population growth of the species of the plants in the respective area.

Predation is a type of interaction where a predator (an organism that is hunting) feeds on its prey (the organism that is attacked). Therefore, intraspecific competition and predation support the growth of plant species. Hence, then the correct answer is option D.
