Q

Ecological Pyramids

A

pyramids that show the relative amount of energy or matter contained within each trophic level in a given food chain

17
Q

Types of ecological pyramids

A

pyramids of energy, pyramids of biomass, and pyramids of numbers

18
Q

Energy Pyramid

A

pyramids that show the relative amount of energy contained within each trophic level in a given food chain

19
Q

Trophic Levels

A

steps in a food chain or food web

20
Q

The 10% Rule

A

10% of the energy available within one trophic level is transferred to the next trophic level

21
Q

Photosynthesis

A

process that plants do by using resources from the environment to create food

22
Q

Balanced Chemical Equation For Photosynthesis

A

6H2O + 6CO2 –(light)-> C6H12O6 + 6O2

23
Q

Where/what do plants store polysaccharides as?

A

in the tissues/as starch

24
Q

Types of Human Interference Disturbance Impacts

A

pollution and overharvesting

25
Q

Pollution results in…

A

bioaccumulation/biomagnification

26
Q

Bioaccumulation/Biomagnification

A

when a pollutant is picked up by an organism and is not broken down or eliminated, and it is collected in the body tissues instead

as producers are eaten and the organisms of trophic levels becomes higher, the more concentrated the pollutant becomes

27
Q

Disturbance Impacts

A

phenomenons that occur and change the natural way of a food web

28
Q

Overharvesting

A

when humans overdo something and kill of a majority of a species

29
Q

Disease (in terms of Disturbance Impacts)

A

naturally occurring sickness that wipes out a majority of a species’ population

30
Q

Introduced Species (in terms of Disturbance Impacts)

A

a new species being added that increases competition with the already present species

31
Q

Climate change (in terms of Disturbance Impacts)

A

changes in the climate that can severely alter the landscape

causes loss of habitat

32
Q

Invasive Species

A

species that are foreign to the environment that dominate the area and becomes harmful to environment

(as a result of introduced species that don’t have a predator in the area)

33
Q

Ecosystems that have greater biodiversity are said to be more resilient. Why?

A

more biodiversity increases the amount of organisms that can be preyed on

If a majority of one species is wiped out, there will still be more food sources that keep the food web stable
