Question 1

ecological succession

Answer 1

succession that changes species to accommodate the ecosystem’s maturity.

Question 2

primary succession

Answer 2

something happens causing everything to restart living from scratch.

Question 3

secondary succession

Answer 3

something happens in which things can be easily rebuilt with the presence of soil

Question 4

The first species to come after a change in the ecosystem. They regrow the community.

Answer 4

pioneer species

Question 5

The changes cause soil to reappear and life to grow.

Answer 5

seral

Question 6

climax community

Answer 6

final community in which species are mature and at their peak

Question 7

species richness

Answer 7

number of different types of species

Question 8

species evenness

Answer 8

abundance/proportion of species

Question 9

genetic diversity

Answer 9

size of population

Question 10

ecological diversity

Answer 10

range of habitat types. variation within ecosystem

Question 11

keystone species

Answer 11

influential ecological organism that exert important effects on other species

Question 12

invasive species

Answer 12

species that aren’t found in the habitat they’re in and cause the community to crumble

Question 13

How do keystone species and invasive species affect biodiversity?

Answer 13

Keystone increases biodiversity and invasive decreases biodiversity

Question 14

Example of primary succession

Answer 14

melting, receding glaciers

Question 15

how can you tell if this succession example of flooding is secondary

Answer 15

the soil remains which allows everything to regrow much easier

Question 16

if a community has 40 for each species found in the area, what would the evenness be?

Answer 16

1

Question 17

what would would the richness be if there was 5 species of that example?

Answer 17

5
