Unit One: Biodiversity

Question 1

What is Biodiversity and why is it important?

Answer 1

Biodiversity is the variety of life found in an ecosystem.
It is important because the higher the biodiversity of an ecosystem, the healthier it is.

Question 2

What are the three types of Biodiversity?
Why are each important?

Answer 2

Genetic Diversity: The different types of genes found in a species. Important because it allows a species to adapt to environmental changes.
Species Diversity: The different species found in an acosystem. Important beacause it allows the ecosystem as a whole to survive drastic changes.
Ecosystem Diversity: The many smaller ecosystems found in a larger one. Important because it allows the ecosystem to support many different species.

Question 3

How do we benifit from biodiversity?

Answer 3

Oxygen, food, clean water and meds

Question 4

What is Taxonomy and its levels?

Answer 4

Taxonomy is the science of naming and classifying living and non living organisms.
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species

Question 5

What are the three domains and their basic discriptions?

Answer 5

Bacteria: Single celled WITHOUT true nucleas.
Archae: Single celled WITHOUT true nucleas but live in extreme conditions.
Eukarya: Multi and unicellular. Have true nucleas.

Question 6

What are the six kingdomes?

Answer 6

Eubacteria, Archae-bacteria, Protista, Fungi, Animalia, Plantae

Question 7

What are the GRAMMIC characteristics?

Answer 7

GRAMMIC is the characteristics of living things.
G - Grow
R - Reproduce
A - Adapt
M - Move
M - Metabolism
I - Irritablity
C - Cells

Question 8

What are the differences between Eukaryotes and Prokaryotes?

Answer 8

Eukaryotes: Multicellular AND unicellular, have a true nucleas, membrane bound organelle. i.e. plants, animals
Prokaryotes: No true nucleas. uncellular, not membrane bound. i.e. bacteria, archae.

Question 9

What are the two prokaryotic kingdoms?

Answer 9

Archae-Bacteria and Eubacteria.

Question 10

What does DNA stand for?

Answer 10

Deoxyribonucleic acid

Question 11

What makes up metabolism

Answer 11

Anabolism(building up complex substances from simpler ones) + Catabolism(breaking down complex substances into simpler ones).

Question 12

What does ATP stand for?

Answer 12

Adenosine Triphosphate.

Question 13

What is Monoculture and its effects?

Answer 13

Monoculture is growing uniform crops on a farm.
Monoculture = less biodiversity and less organisms = more vulnerability to diseases and pathogens.

Question 14

Name the 8 characteristics/qualifications for all living things(not GRAMMIC)?

Answer 14

1. Cells.
2. Reproduction.
3. Metabolism.
4. Homeostasis.
5. Heredity.
6. Responsiveness.
7. Growth and Development.
8. Adapting.
