Q

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

A

Biotic

21
Q

Is it an abiotic or biotic factor: competition

A

Biotic

22
Q

Interspecific competition

A

Between 2 different species (bear vs human for berries)

23
Q

Intraspecific competition

A

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

24
Q

Detritus

A

Decomposing matter (think: both begin with DE)

25
Q

Symbiotic relationships

A

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

26
Q

What are the 5 types of symbiotic relationships?

A

Mutualism, commensalism, parasitism, parisitoidism, and predation

27
Q

Mutualism

A

Mutual benefit to both organisms

28
Q

An example of mutualism

A

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

29
Q

Population

A

A group of 1 species

30
Q

Community

A

More than 1 species

31
Q

Population vs community

A

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

32
Q

Commensalism

A

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

33
Q

An example of commensalism

A

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.

34
Q

Parasitism

A

One organism benefits and the other is harmed

35
Q

Parasite (as in parasitism)

A

The organism that benefits

36
Q

Host (as in parasitism)

A

The organism that is harmed

37
Q

An example of parasitism

A

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

38
Q

Parisitoudism

A

One organism benefits but the other is eventually killed

39
Q

An example of parisitoidism

A

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.

40
Q

Predation

A

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

41
Q

An example of predation

A

When a lion kills a zebra as a source of food

42
Q

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

A

Paradigm
