Flashcards in Chapter One Deck (47):
1

Climate

Average atmospheric conditions of a region

2

climatograph

graphical representation of temperature and precipitation

3

North vs South Rule

Summer temperature is the highest and winter temperature is the lowest

4

Biome

Areas with similar abiotic and biotic conditions

5

Ecosystem

Part of a biome
You can have many ecosystems in one biome

6

Community

The different organisms in an ecosystem

7

Habitat

The place where a critter lives

8

Abiotic

Non living

9

Biotic

Living

10

4 main abiotic factors

Temperature
Latitude
Elevation
Ocean Currents

11

Competition

How living things react

12

Two types of competions

Interspecific (Between different species)
Intraspecific (Between the same species)

13

Species

Organisms that are:
More or less alike
Interbreed under natural conditions
Produce fertile offspring

14

How an organism reacts with its ecosystem

Obtains food from ecosystem
Contributes energy to ecosystem

15

Food chain

A model that shows the flow of energy from living thing to living thing

16

Food Web

A model of the feeding relationships within an ecosystem

17

How a food web and food chain interlink

Food webs are composed of many food chains

18

Trophic levels

The steps in a food chain that show the feeding and niche relationships between organisms

19

Keystone species

Species that can greatly affect the population numbers and health of an ecosystem if removed

20

Top predator

The critter with the longest foodchain

21

biomass

the weight of living material

22

Pyramid of Numbers

Shows the number of organisms at each trophic level

23

Pyramid of Biomass

Shows the number of organisms at each trophic level multiplied by their mass

24

Pyramid of Energy

Shows amount of energy at each trophic level

25

Adaptions

Special traits that help living organisms survive/reproduce in an ecosystem

26

Structural Adaptaion

physical traits on a critter's body

27

Physiological Adaptation

Physical/chemical event that takes place inside the body of an organism

28

Behavioural Adaptaion

Actions an organism takes in order to survive.
Includes how it: Mates, feeds, and cares for young.

29

Niche

The special role an organism plays in an ecosystem including the way it contributes/fits into the environment, as wells as all the interactions it needs in order to grow/survive/reproduce

30

Difference between a niche and a habitat

A habitat supports many different types of species and holds many niches. A single niche supports one species and is found in a habitat.

31

Bioaccumulation

The build-up of chemicals in an organism

32

Biomagnification

The process where chemicals become more concentrated at each trophic level.

33

Herbivory

plant eater

34

Predation

One kills another

35

Symbiosis

Relationships between two critters

36

4 examples of symbiosis

Parasitism
Mutualism
Commensalism
Amensalism

37

Parasitism

One benefits, one harmed

38

Mutualsim

Both benefit

39

Commensalism

One benefits, one isn't harmed nor benefits

40

Amensalism

One benefits by making a chemical to keep others away

41

Autotroph

Makes own food

42

Heterotroph

Eats food

43

Omnivore

Eats plants and meat

44

Detritivore/decomposer

Breaks down dead things

45

Herbivore

Eats plants

46

Carnivore

Eats meat

47

Saphrophyte

Eats dead things
