ch 20+21 biodiversity Flashcards
1
Q
ecosystem ecology
A
- study of living and non-liovinvg things
- studies how nutrients and energy are stored move along organisshm
2
Q
Food chains
A
- linear sequence of how organisms nutrients and energy are pass thru as one eats the other
3
Q
Apex/Terteriary Trophic Level
A
- top of the food chain
- usually carnivores
- carnivores that eat other carnivores
-ex humans. me
4
Q
Secondary Trophic Level
A
- carnivores eating primary consumers
5
Q
Primary Consumers
A
- organisms lower on food chain that eat only producers
- herbivores
6
Q
Producers
A
- base of food chain
- photoysnthetic tings
7
Q
how mcuh energy is passed thru Food Chain
A
10 %
8
Q
Food Webs
A
- more accurately depecting multiple feeding interactions
- cuz multi organisms eat multi things
9
Q
Grazing Food Web
A
- hs plants at the base of web
10
Q
Detrital Food Web
A
- has carcasses n decomposers at base of web
ex. dead ppl, bacteria, fungi
11
Q
how do autotrophs and heterotrophs acquire energy
A
Auto = thru sunlight or chemical energy
ex. Photosyn (sun) or Chemosyn (archea using inorganic mats)
Hetero =- thru consuming other organisms
12
Q
Biogeochemical Cycles
A
- energy flwoing trhu ecosystems from sun to water to heat to vapor
13
Q
Biologcial Carbon Cycle
A
- rapid carbon cycle
- Carbon used as BASIC building block for every orgnaism fr
14
Q
Biogeochemical Carbon cycle
A
- longer
- Carbon stored in resevoirs for long periods of time
ex. atmosphere, oceans, rocks, soil, fossil fuels - used for photosynthesis
15
Q
how is carbon invovled with Climate Change
A
- as carbon increases, heat does
