Question 1

do plants use k/r selection

Answer 1

no

Question 2

grime theory

Answer 2

how plants succeed in environments

Question 3

3 categories of grimes

Answer 3

stress tolerators, competitors, ruderals

Question 4

stress tolerator

Answer 4

high stress low disturbance, small/perennial plants, invest energy to resources

Question 5

stress habitats

Answer 5

salt marsh, poor resources, low competition as less plants

Question 6

competitors

Answer 6

low stress/disturbance, perennials/fast growing plants, neighbouring plants use same resources

Question 7

competitor habitats

Answer 7

lots of resources, rainforest

Question 8

ruderals

Answer 8

high disturbance, low stress, short lifespan

Question 9

ruderal habitats

Answer 9

pavements, dunes

Question 10

primary succession environments

Answer 10

lava/volcanic islands, exposed rock/inital rock (pavements)

Question 11

Answer 11

pavements/sand etc are harsh environments where only certain plants can live (lichens), as soon as they die soil forms and new plants move in building nutrients/shade/water

Question 12

lichens

Answer 12

first colonisers make ecosystems, some are nitrogen fixing, help break down rock

Question 13

intermediate stage

Answer 13

after initial stage, more plants grow, sand dunes

Question 14

climax community

Answer 14

last community, most biomass possible, usually not achieved
