the science of grouping organisms

Question 6

what is a taxon?

Answer 6

a group of organisms that share similar features

Question 7

what is an ecological niche?

the role that a species plays in a particular habitat and how it uses the resources.

Question 8

what is an ecosystem?

Answer 8

the combination of biotic and abiotic features in an area

Question 9

includes all individuals of all species that live in a particular area

Question 12

how does water availability impact the environment?

Answer 12

Drainage, over abstraction of aquifers, hydroelectric power

Question 13

how does Dissolved oxygen impact the environment?

Answer 13

dissolved oxygen can be reduced by hot water from power stations which affects fish and other aquatic animals

Question 14

how does Temperature (climate) impact the environment?

Answer 14

Affects the distribution of species

Question 15

how does Temperature (water) impact the environment?

Answer 15

affects the growth rates of vegetation, or increases decomposition rates

Question 16

how does pH impact the environment?

Answer 16

Affects growth rate and can denature cell proteins/ erode shells

Question 17

how does Water turbidity impact the environment?

Answer 17

Ploughing, mining, dredging increase it, reducing light penetration, affecting photosynthesis

Question 18

how are Pollinators impacted by human activities?

Answer 18

Affected by use of pesticides, reducing populations

Question 19

why are seed dispersal species important?

Answer 19

Many are endangered, can be through faeces or droppings, or sticking to fur.

Question 20

how do Food chain impacts affect the environment?

Answer 20

Over-exploitation of one species can allow the increase of another species, either a competitor or prey.

Question 21

how do introduced competitors impact the environment?

Answer 21

makes native species compete for resources

Question 22

how do introduced predators impact the environment?

Answer 22

reduces populations of the prey species

Question 23

what are introduced pathogens?

Answer 23

a non native disease introduced to control or eradicate a species

Question 24

how does hybridisation impact ecosystems?

Answer 24

cross-breeding between species resulting in infertile offspring

Question 25

how does a loss of species that control abiotic factors impact the environment?

Answer 25

affects other species relying on those specific abiotic factors, e.g. elephants create clearings and watering holes, beavers build dams

Question 26

what are examples of habitat destruction?

Answer 26

deforestation, ploughing grassland, reservoirs, mineral extraction, urban expansion

Question 27

Answer 27

species that influences the survival of many other species in an ecosystem

Question 28

what are Vavilov centres?

Answer 28

A centre for the domestication of plants

Question 29

What do biological corridors do?

what are ramsar sites?

Answer 33

They contain rare/important wetland types

Question 34

what is vegetation age structure?

Answer 34

The measure of how old vegetation is e.g. Dendrochronology, counting rings on trees
