Abiotic

Question 17

Is it an abiotic or biotic factor: inorganic and organic soil nutrients

Answer 17

Abiotic

Question 18

Answer 18

Biotic

Question 19

Is it an abiotic or biotic factor: disease

Answer 19

Biotic

Question 20

Is it an abiotic or biotic factor: predator/ prey interaction

Answer 20

Biotic

Question 21

Is it an abiotic or biotic factor: competition

Answer 21

Biotic

Question 22

Interspecific competition

Answer 22

Between 2 different species (bear vs human for berries)

Question 23

Intraspecific competition

Answer 23

Within same species (ex: fox vs fox for rabbit)

Question 24

Detritus

Answer 24

Decomposing matter (think: both begin with DE)

Question 25

Symbiotic relationships

Answer 25

Biotic relationships in which 2 different organisms live in close association with each other to the benefit of at least 1

Question 26

What are the 5 types of symbiotic relationships?

Answer 26

Mutualism, commensalism, parasitism, parisitoidism, and predation

Question 27

Mutualism

Answer 27

Mutual benefit to both organisms

Question 28

An example of mutualism

Answer 28

The algae and fungus of lichens. The fungi make soil nitrogen available to the plant, receiving carbohydrates in return.

Question 29

Population

Answer 29

A group of 1 species

Question 30

Community

Answer 30

More than 1 species

Question 31

Population vs community

Answer 31

Population is a group of 1 species. Community is more than 1 species.

Question 32

Commensalism

Answer 32

One organism benefits from the relationship but the other organism seems neither to be harmed nor benefited

Question 33

An example of commensalism

Answer 33

A beaver and a fish. A beaver builds a dam (to regulate water level) to help survive in the winter and fish often inhabit the pond. The fish benefit from the never but the beaver is neither harmed or benefitted.

Question 34

Parasitism

Answer 34

One organism benefits and the other is harmed

Question 35

Parasite (as in parasitism)

Answer 35

The organism that benefits

Question 36

Host (as in parasitism)

Answer 36

The organism that is harmed

Question 37

An example of parasitism

Answer 37

Tapeworm. They live in the digestive tracts of organisms while they are provided with nutrients and an environment to grow and reproduce. The host is harmed by the presence of the tape worm

Question 38

Parisitoudism

Answer 38

One organism benefits but the other is eventually killed

Question 39

An example of parisitoidism

Answer 39

When a female wasp stings a spider causing paralysis (not death.) the wasp then lays an egg on the spider. When the egg hatches it slowly eats the body of the spider, slowly killing it.

Question 40

Predation

Answer 40

Where the interaction is beneficial to one species and detrimental to the other

Question 41

An example of predation

Answer 41

When a lion kills a zebra as a source of food

Question 42

The way that humans view the world is known as a:

Paradigm
