Bio diversity - Topic One

Question 1

Species

Answer 1

Group of organism that have same structure and can reproduce with one another

Question 2

Structure (biological)

Answer 2

Body parts that serve some function/purpose

Question 3

Insect species

Answer 3

More inspect species than all life forms combined,

30-100 million different species but only know a small amount

Question 4

Biological diversity

Answer 4

All organisms share characteristics of life (cells, energy, grow & develop, reproduce and adapt)
Diversity refers to the differences between species

Question 5

Factors that affect biological diversity

Answer 5

Abiotic and biotic from ecosystems

Question 6

Population

Answer 6

Species living in a specific area and use the same resources.

Question 7

Species diversity

Answer 7

Even among species no two organisms are exactly identical, they have variation

Question 8

Populations of different species living in the same area is called

Answer 8

Community

Question 9

Variations?

Answer 9

Influenced by genes
Can be seen or not seen
(Ex;)

Question 10

More diversity? Why?

Answer 10

Closer to the equator
Higher number of plant life, more variety of animal organisms

Question 11

When classifying name? Species

Answer 11

Species second word used, species we belong to

Question 12

Why use Latin to classify system?

Answer 12

Scientific language at the time,
Now dead langauges can’t change

Question 13

When classifying name? Genus

Answer 13

Genus first word used to notate which group the organisms belongs to.

Question 14

Can two species have the same name?

Answer 14

No

Question 15

Closely related species can have same genus?

Answer 15

Yes

Question 16

Classifying based off of? What was the Old way?

Answer 16

Linnaeus group organisms based off of physical appearance.

Old way was location.

Question 17

Linnaean Taxonomy, order, and why?

Answer 17

Most general to least general.
1. Kingdom(s)
2. Phyla/Phylum
3. Class(es)
4. Order(s)
5. Family/Families
6. Genus/Genera
7. Species

Question 18

Biological diversity under the sea: coral reefs

Answer 18

Coral reefs contain many different communities
Considered “amazons of the oceans”

Question 19

Biological diversity under the sea: coral polyps

Answer 19

Coral polyps are living layer under coral reef

Question 20

Biological diversity under the sea: algae

Answer 20

Algae lives here and provides energy for the coral community

Question 21

Biological diversity under the sea: Calcium Carbonate Layer

Answer 21

Calcium carbonate layer of reefs constructed by reef-building coral and some algae

Live for thousands of years and can be big

Question 22

Interdependence

Answer 22

Organisms relying on other species to survive

Question 23

Mutualism

Answer 23

Both organisms benefit

Ex: lichen contains fungus and alga
Ex: alga produce good while fungus prevents them from dying

Question 24

Commensalism

Answer 24

One organism benefits while the other is not harmed
Ex: barnacles attached onto whales to move, while whale is not armed

Question 25

Parasitism

Answer 25

One organism benefits while the other is harmed Ex: tapeworm in humans, where the human is harmed Parasites do not want to kill host Can have more than one host Ex: Mexican bean beetle is a plant parasite, but infected with tachinid fly

Question 26

Interspecies competition

Answer 26

No species benefit since both are competing for limited resources

Question 27

Niche

Answer 27

Role of organism within ecosystem Ex: what it eats, what eats it, habitat, nesting site, range Can differ from area to area

Question 28

Resources partitioning

Answer 28

Divide resources accordingly to niches Ex: warbler species eating same worm, but in different locations of trees Doesn’t always have to be for food can be for habitat

Question 29

Variation

Answer 29

Variability in differences in characteristics Ex: hair colour, size, blood type, etc

Question 30

Variability for survival

Answer 30

If disease, predator, or external factor threatens species, having variability may lead to survival

Question 31

Natural selection

Answer 31

Nature/environment selects which organisms reproduce Ex: bigger and more symmetrical birds survived to reproduce - maybe because had more fat and was able to waste less energy since they’re symmetrical
