1
Q

Biomagnification

A

The process in which chemicals not only accumulate but become more concentrated at each trophic level of the food pyramid

2
Q

Key stone species

A

Species (salmon) that can greatly affect population numbers and the health of an ecosystem

3
Q

Heavy metals

A

Metallic element with a high density that are toxic to organisms at low concentration

4
Q

Bioaccumulation

A

The gradual build up of synthetic and organic chemicals chemicals in living organisms

5
Q

Ecological succession

A

Changes that take place over time in types of organisms that live in a area.

6
Q

Pioneer species

A

The first organisms to populate, or repopulate an area after a disturbance in the ecosystem

Ex. Lichen, moss, bacteria, or algae

7
Q

Primary succession

A

The development of new life in areas where no organisms or soil previously existed. The first organism are usually lichen and bacteria delivered by bird poop!

8
Q

Secondary succession

A

The REINTRODUCTION of life after a disturbance to an area that already has soil and was once the home of living organisms.

9
Q

Climate community

A

A mature community /ecosystem/biome such as boreal or grass lands that change slowly though constant over time

10
Q

Natural selection

A

The process by which, over time the best adapted members of a species survive and reproduce. This process makes gradual change in species possible.

11
Q

Adaptive radiation

A

The development of a number of new species from a common ancestor. The new species are adapted to inhabit different niches.

12
Q

Flooding

A

Soil erosion, pollution, disease from toxic bacteria or untreated sewage.

13
Q

Drought

A

Plants and animals die due to lack of water

14
Q

Tsunamis

A

Huge rapidly moving ocean waves destroys habitats and salt water is carried onto the shore which change soil chemistry

15
Q

Hurricane

A

Destroys large plants and disrupt animal habitats

16
Q

Forest fire

A

Destroy vegetation and habitats returns nutrients to the soil

17
Q

Volcanoes

A

Ash clouds can affect sun light and destroy all organic matter it comes in contact with. Toxic ash can affect ecosystem.

18
Q

Insect infestation

A

Often results in succession in forest because insects destroy older trees.

19
Q

Invasive species

A

Introduced or foreign species that are natural to an ecosystem. They often dont have predators

20
Q

Compotion

A

Invasive species can often reproduce rapidly often aggressive lack natural predators

21
Q

Predation

A

If you introduce a new predator, prey species do not have the adaptations to defend against it

22
Q

Disease and parasites

A

Parasites or diseases causing viruses and bacteria can weaken immune system of native plants and animals

23
Q

Habitat alteration

A

Introduced invasive species can make a natural habitat unsuitable for native species by changing his structure or composition

24
Q

Traditional ecological knowledge

A

Ecological information passed down from generation to generation that reflects human experiences with native gained over centuries

25
Q

Proton

A

Subatmoic particals that have a 1+ positive charge

26
Q

Neutrons

A

Subatomic particles that do not have a electric charge

27
Q

Electrons

A

Subatomic particles that have a 1- electric charge

28
Q

Period

A

Each row of elements in the periodic table

29
Q

Ions

A

Electrically charged particles created when atoms gain or lose electrons

30
Q

Bohrs diagram

A

A diagram that shows the arrangement of an elements subatomic particles and the number of electrons in each shell surrounding the nucleus of an atom

31
Q

Stable octet

A

The arrangement of eight electrons in the outermost shell of an atom

32
Q

Niche

A

The special role an organism plays in an ecosystem, including the way in which contributes to and fits into its environment

33
Q

Mimicry

A

When an organism copies another in attempts to gain benefits

34
Q

Soil compaction

A

The squeezing together of soil particles so that the air spaces between them are reduced

35
Q

Biomass

A

The total mass of living plants, animals, fungi, and bacteria in a given area

36
Q

Carbon cycle

A

The nutrient cycle in which carbon is moved throuh the biosphere

37
Q

Carbonate

A

A combination ion of carbon and oxygen that is dissolved in ocean water

38
Q

Cellular respiration

A

The process in which both plants and animals released carbon dioxide back into the atmosphere

39
Q

Soil degradation

A

The damage to soil. For example it is the result of deforestation when topsoil is removed

40
Q

Contamination

A

The introduction of chemicals, toxins, wastes, or micro organism into the environment that are harmful to the ecosystem
