Flashcards in Chapter 54 Deck (34):
1

Indicate how each inter specific interaction affects the survival and reproduction of the 2 species interacting

+ and -

2

(-/-)
Occurs when individuals of different species compete for a resource that limits their growth and survival

Interspecific competition

3

Conditions which leave to competitive exclusion

Limited resources
Multiple species competing

4

One species outcompetes the other, which goes extinct

Competitive exclusion

5

Two species with the exact same niche

Perfect competition

6

All of the resources a species uses make up its

Ecological niche

7

Dividing up of a resource

Resource partitioning

8

How does resource partitioning relate to competitive exclusion?

Helps species overcome compatible exclusion and coexist

9

Conditions under which a species could exist without competition

Fundamental niche

10

Conditions under which a species actually exists

Realized niche

11

When two species are together, they become more distinct

Character displacement

12

Because of character displacement, sympathetic populations tend to be ___ similar to each other than allopathic populations of the same two species

Less

13

(-/+)
Between species in which one species, the predator, kills and eats the other, the prey

Predation

14

I I pull a carrot from my garden and eat it is it predation?

Yes

15

Four behavioral defenses

Camo
Warning coloration
Batesian mimicry
Millerian mimicry

16

Makes animals hard for predators to see

Cryptic coloration

17

Wants predators that an animal is toxic

Aposematic

18

A harmless species mimics an unpalatable or harmful species

Batesian mimicry

19

Two or more harmful/unpalatable species mimic each other

Mullerian

20

Which type of mimicry benefits everyone

Mullerian mimicry

21

(-/+)
An organism eats parts of a plant or alga

Herbivory

22

Two structural defenses

Spines
Thorns

23

Two chemical defenses

Strychnos toxifera
Astragalus

24

Can the term symbiosis describe harmful interactions

Yes

25

(-/+)
One organism, the parasite, derives its nourishment from another organism, it's host , which is harmed in the process

Parasitism

26

Feed off the external surface

Ectoparasites

27

Love within the body

Endoparasites

28

(+/+)
Benefits both species

Mutualism

29

At least one party can't survive without the other

Obligate mutualism

30

Both can survive on their own

Facultative mutualism

31

(+/0)
Benefits one but neither harms nor helps the other

Commensalism

32

Is true commensalism common in nature?

No

33

(+/+) or (+/0)
Can have positive effects on survival and reproduction of other species without necessarily living in direct intimate contact
Not sybiotic

Facilitation

34

Competition, predation, her ivory, symbiosis, and facilitation

Interspecific actions
