5.1.2 - Biotic & Abiotic Factors

Question 1

What Are Abiotic Factors?

Answer 1

Non-living factors that influence populations within their community.

Question 2

What Are Examples Of Abiotic Factors?
(4 Points)

Answer 2

~ Light intensity.

~ Temperature.

~ Moisture levels.

~ Wind intensity.

Question 3

What Varies Due To Abiotic Factors?

Answer 3

The abundance of species.

Question 4

When Abiotic Conditions Are Ideal For A Species, What Can Happen & Give An Example?
(3 Points)

Answer 4

~ Organisms can grow fast and reproduce successfully.

~ Ideal temp means that metabolic reactions don’t use up as much energy to maintain body temperature, this energy can be used for growth to increase abundance.

~ Vice versa.

Question 5

What Are Biotic Factors?

Answer 5

A living factors that influence populations within their community.

Question 6

What Are Examples Of Biotic Factors?
(5 Points)

Answer 6

~ Predation.

~ Food availability.

~ Intra and interspecific competition.

~ Parasitism.

~ Disease.

Question 7

What Is Meant By Interspecific Competition?

Answer 7

Competition between different species.

Question 8

How Does Interspecific Competition Lead To Lower Abundance For Both Species Involved?
(4 Points)

Answer 8

~ Resources available to both populations are reduced.

~ Populations will be limited by a lower amount of food.

~ They will have less energy for growth and reproduction.

~ Lower abundance for both species.

Question 9

What Is Meant By Intraspecific Competition?

Answer 9

Competition within a species.

Question 10

How Does Intraspecific Competition Lead To Lower Abundance For A Species?
(5 Points)

Answer 10

~ Population size increases when there is more resources.

~ As populations increases there will be more organisms competing for the same amount of space and food.

~ Eventually these resources will become limited.

~ Leading to lower abundance for the species.

~ This depends on the size of the population.
