Q

Body Symmetry

A

Asymmetry -animal cannot be divided into equal halves
Radial-round animals that can be cut into equal parts by multiple planes as long as it goes through the middle
Bilateral -animals that can be cut into equal halves but only by 1 plane (mammals)

Q

Parasitism

A

+/- relationship

19
Q

Parasitism vs parasitoid

A

Parasitism - don’t usually kill their host
Parasitoid - do kill host in the end

20
Q

Scramble competition

A

Competitor targets the resource

21
Q

Interference competition

A

Competitors targets each other and not the resource
Interferes with your ability to get the resource

22
Q

Density dependent growth

A

Intraspecfic competition

23
Q

Fundamental niche

A

Everything a species wants

24
Q

Realized niche

A

Everything a species gets

25
Q

Exploitative interactions

A

+/- relationship

26
Q

Standing defenses

A

Defenses that are there regardless if the predator is there or not

27
Q

Inducible defenses

A

Those that are there only if the predator is present

28
Q

species diversity

A

how many species are in an area and the abundance of each (%)

29
Q

species richness

A

how many diff species there are in an area

30
Q

primary succession

A

the growth of new things where there was no soil before and must be grown new

31
Q

secondary succession

A

growth of new plants where soil already remained

32
Q

facilitation (sucession)

A

one species makes it easier for the subsequent species to live in some habitat

33
Q

tolerance

A

later succession species show greater tolerance than younger succession plants
shrubs are more tolerant of shade than herbs

34
Q

inhibition

A

older succession plants inhibit early succession plants

35
Q

keystone species

A

species that have a greater impact on the diversity an species richness in their community than you would predict based on biomass

36
Q

Bergman’s law

A

the colder an area the bigger animals are usually

37
Q

carnivory

A

the eating of other animals by a predator
animals are higher in fats and protein
carnivores have simpler digestove systems

38
Q

protostome

A

blastopore becomes a mouth

39
Q

deuterostome

A

blastopore becomes an anus

40
Q

ecdysozoan

A

grows by shedding outer layer

41
Q

lophotorocozoan

A

grows by adding increments to the body (flatworms)

42
