Question

Which of the following best explains how a biotic factor can control the population of a species in an ecosystem?

A sudden drop in temperature may cause many individuals in a population to die.
Competition between two species may force one of them to migrate to survive.
Disease may lead to a decline in the reproductive rate of the species’ main predator.
Lack of water during a drought may cause many of the individuals in a population to die.

Cardinal What do you think?

Answer 15

Well.. competition makes a lot of sense though.

Answer 16

Can you explain why?

Answer 17

A biotic factor is any living component that affects other organisms, including animals that consume the organism in question, and the living food that the organism consumes. Each biotic factor needs energy to do work and food for proper growth. Biotic factors may include human influence.

Although they may be as equally limiting to a population of species, a drop in temperature or a reduction in water supply (a.k.a. drought) is an ENVIRONMENTAL factor, not a biotic one. We can cross out A and D.

Answer 18

Ok so would the answer C

Answer 19

I meant B

Answer 20

Precisely. Disease is caused by microorganisms (a biotic limiting factor), and if it reduces the population of the species’ main predator, the population of the predated species (or prey) will experience an increase in number. Reduction of predators is a BIOTIC factor. C is your best answer.
