Abundance and Distribution of organisms

Question 1

What is abundance?

Answer 1

• the number of individuals of a single species in an ecosystem/habitat.

Question 2

What is distribution?

Answer 2

• where a species is found in an ecosystem/habitat

Question 3

What is intraspecific competition?

Answer 3

• competition within a species

Question 4

what is carrying capacity?

Answer 4

• the max stable populations in an ecosystem can support

Question 5

what is a limiting factor?

Answer 5

• the thing that limits max population size

Question 6

what is interspecific competition?

Answer 6

• competition between species

Question 7

What happens to species with a similar niche?

Answer 7

• species with a similar niche will compete for resources e.g.blue tit + great tit

Question 8

What happens to the abundance in interspecific competition?

Answer 8

• the abundance of one species will affect the others

Question 9

What happens to the niche in intraspecific competition?

Answer 9

• they occupy the same niche -> Compete for everything e.g. food/mates

Question 10

what can we say about abiotic factors, mentioning about conditions?

Answer 10

• species can tolerate a range of conditions
• where conditions are optimal -> population will be the biggest

Question 11

What do interspecific competition and predation offer?

Answer 11

• interspecific competition and predation will offer an organism distribution.
• organisms will only exist whether they can survive e.g. no penguins in the Caribbean
