science 9: Biological Diversity

Question 0

Biodiversity

Answer 0

The entire collection of living organisms on earth, each with their own characteristics.

Question 1

Species

Answer 1

A particular group of organisms that have the same structure and can reproduce with each other. The most identified species is insects!

Question 2

Biological diversity

Answer 2

The variety of species and ecosystems on the earth and the ecological processes they are part of.

Question 3

Main components of biodiversity

Answer 3

Ecosystem diversity, community diversity, species diversity, genetic diversity, species distribution

Question 4

Ecosystem diversity

Answer 4

Different types of living communities and the environments in which they are found.

Question 5

Community diversity

Answer 5

Occurs within populations of organisms living in a particular ecosystem.

Question 6

Species diversity

Answer 6

Occurs within individual organisms of the same species.

Question 7

Genetic diversity

Answer 7

Occurs within organisms at a cellular level, as it describes the variety of the genetic material in all living things.

Question 8

Species distribution

Answer 8

Plants and animal species are not distributed evenly throughout various Eco- regions of the world. There would be most species of plants and animals in the hotter rainforest than closer to the poles.

Question 9

Diversity classification

Answer 9

Developed by Carolus Linnaeus in the 18th century
More reliable because it uses structure rather than the habitat of organisms
Genus and species identify the organisms

Question 10

Five kingdoms of Classification

Answer 10

Animalia- animals
Plantae- plants
Fungi- mushrooms, ect
Protista- single called organisms 
Monera- bacteria

Question 11

Subdivided five Kingdoms

Answer 11

Kingdom
Phylum
Class
Order
Family
Genus
Species

Question 12

Biodiversity under the sea

Answer 12

Coral reefs are great bio diversities. Like rainforests coral reefs support many different communities with little nutrients that gets recycled.

Question 13

Interdependence

Answer 13

Each and every species depends on many other species within its environment in order to survive and prosper. Food chains and webs represent the on going relation ships between different species.

Question 14

Symbiosis

Answer 14

Different type of interdependence within a certain population or community between members of different species.

Question 15

Commensalism

Answer 15

One organism benefits and the other is neither harmed nor benefited
Bird nesting in a tree.

Question 16

Mutualism

Answer 16

Both organisms benefit

Bee and flower.

Question 17

Parasitism

Answer 17

One organism benefits and the other is harmed

Tapeworm in humans

Question 18

Interspecies competition

Answer 18

Happens when two or more species need the same resource. This helps limit the size of populations with competing species
All the african animals needing to drink from the same watering hole.

Question 19

Niche

Answer 19

Role of an organism within a particular ecosystem. A niche includes:
What it eats, what eats it, it’s habitat, nesting site, effect on other populations, effect on own environment.
Niches can change depending on its environment.

Question 20

Resource partitioning

Answer 20

Action which enables competing species to share the resources by accessing these resources different ways, involving less competition.
Ex. Different warbler species eating from different parts of the tree.

Question 21

Variability

Answer 21

Variation within a population, within a species. Important in the environment in which the species lives, changes. When a species has a great deal of variation than others within that species will likely survive to change.
Ex: red fox colour of coat, banded snail shells

Question 22

Natural selection

Answer 22

Happens when factors in the environment determines which individuals in a species will survive. If they are able to survive and reproduce, those individuals will have new adaptations and thrive.
Ex. Larger bird survives harsh weather than smaller birds
