the study of living things and all the other factors around them in an ecosystem

Question 2

ecosystems

Answer 2

refers to everything that affects an organism throughout its life
what the organism affects

Question 3

Answer 3

a natural home or environment of an organism, plant or animal

Question 4

biotic

Answer 4

living
- density-dependent: depend on population size

Question 5

abiotic

Answer 5

non-living or inanimate
- density-independent: dont depend on population size

Question 6

what is a biosphere

Answer 6

the land air and water of earth
- all biomes on earth

Question 7

what is a species

Answer 7

similar organisms that can breed and produce viable offspring

Question 8

viable

Answer 8

can have their own kids

Question 9

what is an individual

Answer 9

an organism from a specific species

Question 10

what is a population

Answer 10

a population is a group of individuals of the same species

Question 11

what is a community

Answer 11

all populations of habitat

Question 12

ecologists

Answer 12

scientist who study the interactions of organisms with one another and their environment
- ex: individuals, populations and ecosystems

Question 13

individual ecologists

Answer 13

• studies the abiotic factors that can change an individuals behavior or physical features

Question 14

population ecologists

Answer 14

describe changes in the size of a population, its abundance as time goes by
- why a population changes
what factors determine the relative numbers of males and females in a population

Question 15

community ecologist

Answer 15

study interactions between the populations/species
> competition between individuals of the same or between species
> abiotic factors that affect the living conditions of populations that live there
- why some communities are more diverse
> competition between individuals of the same or in between species

Question 16

communities are ____

Answer 16

dynamic
(constant change)

Question 17

Organization of the biosphere

Answer 17

1. individuals
2. population
3. communities
4. ecosystem
5. biome
6. biosphere

Question 18

Succession
- what is it
- how many

Answer 18

ecosystems aren’t static ( still )
theyre always changing

Question 19

first succession
1)
2)
3)
and example

Answer 19

starting from scratch
- little to no soil

pioneer species →→→→→→→climax community

1) pioneer species first to settle in an ecosystem( trees)
> soil fermentation
2) populations get replaced by diff. populations
3) most stable; slowest growing

ex) life after volcanic eruptions

Question 20

secondary succession
1)
2)
3)
and ex

Answer 20

there is soil present

1. 2. 3. pioneer (grass)→→→→climax community
2. different from 1 con
3. populations get replaced by other populations
4. most stable; slow growing

ex) forest fire(wildfire)

Question 21

Taxonomy

Answer 21

classifying living things

Question 22

taxonomy levels
Dope Kings Play Cards On Friday Generally Stone

Answer 22

Domain
Kingdom
Phylum
Class
Order
Family
Genus
species(most exclusive)

• the more levels you have the more closely related you are

Question 23

binomial nomenclature

Answer 23

the naming system in which the bottom two levels are used for naming
- genus and species

Question 24

Aristotle’s classifications

Answer 24

1. plants and animals
   > kingdom plantae and kingdom animalia
2. Animalae, Plantae, Protista
3. Eukarya, Bacteria, Archaea (← within those 3 domains there are 6 kingdoms of life)

Question 25

3 Domains

Answer 25

Archea Bacteria Eukarya

Question 26

6 Kingdoms

Answer 26

Archaea Bacteria Plantae (absorb, produce) Animalia Protists (microscopic organisms) Fungi (heterotrophic, dont reproduce)

Question 27

dichotomous keys

Answer 27

arranged in steps with two statements per step to find out the species or name it if it hasnt been found

Question 28

what is range

Answer 28

total geographical area an organism can find a suitable habitat

Question 29

niche - ecological niche

Answer 29

an organism’s **role** in its environment and its relationship with the ecosystem

Question 30

What does a species’ niche include

Answer 30

Habitat: where they live Relationships: Its interactions with other species in the ecosystem Nutrition: How it obtains food

Question 31

density

Answer 31

the number if individuals per unit of volume or area

Question 32

biodiversity

Answer 32

the variety of life in a habitat or ecosystem. The greater the biodiversity, the less competition there is for any niche

Question 33

what determines the distribution of populations is controlled by ___

Answer 33

limiting factors - biotic and abiotic factors

Question 34

biotic limiting factors

Answer 34

**symbiosis** - mutualism: both benefit - commensalism: only one benefits but the other is unaffected - parasitism: one benefits but the other is harmed **predator-prey** **competition** interspecific and intraspecific

Question 35

interspecific and intraspecific

Answer 35

interspecific: competition between different species intraspecific: competition between the same species

Question 37

estimating population size

Answer 37

1. calculate total number size - add all data 2. avg trees per section total / how many diff sections 3. how many sections in forest calculate a section and then total area divided by one section 4. estimation (avg tree per section ) (total sections)
