Q

Decomposer

A

Break down dead organisms and waste. They recycle the energy making the energy come back to the soil

Q

Food Webs

A

Show many food chains interconnected together

17
Q

Food chains

A

The transfer of energy from one organism to another in a community

18
Q

Primary Consumer

A

They eat producers and herbivore

19
Q

Secondary Consumers

A

They eat primary consumers.

20
Q

Third Consumers

A

They are omnivores. Apex. At the top of the food chain or energy pyramid

21
Q

Cell Respiration

A

Way to get energy. C6 H12 O6+O2 = ATP + CO2 + H2O

22
Q

Parasitism

A

Parasite benefits and host is affected negatively

23
Q

Mutualism

A

Both benefit

24
Q

Commensalism

A

One benefits and the other is unaffected

25
Energy pyramid 1
Shows the relative amount of energy available at each trophic level
26
Habitat
The place where an animal or plant lives
27
Biome
Group of terrestrial ecosystems that have the same climate & communities
28
Limiting factors
Anything that restricts the size of the population. 2 types of limiting factors: Biotic and Abiotic
29
Biotic Factors
Competition: The best adapted will increase and the other will die out or move out Indirect competition: Struggle for resources among organisms in an ecosystem
30
Abiotic Factors
Amount of: Energy, temperature, water, carbon dioxide, oxygen, soil, nutrients
31
What happens if 2 organisms occupy the same niche?
Organisms would compete until the best adapted wins Organisms can appear to occupy the same niche, but under more careful observation, they do not.
32
Circle of life
All things are dependent on one another
33
Primary Succession
When an ecosystem develops for the very first time. There is no soil
34
Secondary Succession
When an ecosystem is destroyed and then re-grows over time
35
Pioneer species
The first group of organisms that inhabit an ecosystem
36
Destruction of Climax Communities
Wildfire, Volcanic eruptions, Floods, Deforestation, Tornadoes, Mudslides, Acid rain, etc.
37
Aerobic respiration
Oxygen + Sugar= Carbon dioxide + Energy + Water
38
Photosythesis
Carbon dioxide + Water= Oxygen + Sugar
39
Nitrogen
Component of DNA and protein
