Q

Coral Bleaching

A

A phenomenon where corals lose their symbiotic algae (zooxanthellae), often due to stress from factors like increased water temperature, leading to a loss of color and potential coral death.

29
Habitat
Where an organism lives.
30
Niche
The role an organism plays in its ecosystem
31
Symbiosis
Close interaction between species.
32
Mutualism
Both benefit
33
Parasitism

34
Commensalism
One benefits, the other is unaffected
35
Predation
One organism (predator) eats another (prey).
36
Competition
Organisms vie for the same resources.
37
Biodiversity
Variety of life; important for ecosystem resilienc
38
HIPPCO
Habitat Destruction Invasive Species Pollution Population Growth Climate Change Overexploitation
39
Generalist
Can thrive in a variety of environments (e.g., raccoons).
40
Specialist
Thrive in specific conditions (e.g., pandas).
41
Autotroph
Organisms that produce their own food (e.g., plants).
42
Heterotroph
Organisms that consume other organisms (e.g., animals).
43
Trophic Levels
Levels in a food chain (producers, consumers, decomposers).
44
10% Rule
Only 10% of energy is passed to the next trophic level.
45

46
Carbon Cycle
Photosynthesis, respiration, combustion, fossil fuels.
47
Human Impact in the Water and Carbon Cycles
Pollution, deforestation.
48
Invasive Species
Non-native species that harm ecosystems (e.g., Cane Toad in Australia).
49
Keystone Species
Species that have a large impact on their ecosystem (e.g., wolves in Yellowstone).
50
Evaporation
The process where water changes from liquid to gas (vapor) due to heat.
51
Precipitation
Water released from clouds as rain, snow, sleet, or hail.
52
Condensation
The process where water vapor cools and changes back into liquid droplets, forming clouds.
53
Runoff
Water that flows over the surface of the land into bodies of water like rivers, lakes, and oceans
54
Photosynthesis
The movement of water through soil and porous rock into underground reservoirs.
55
Infiltration
The process by which water on the ground surface enters the soil.
56
Aquifer
An underground layer of rock or sediment that holds water.
57
Photosynthesis
The process by which plants use sunlight, carbon dioxide (CO₂), and water to produce glucose (sugar) and oxygen.
58
Respiration
The process by which organisms convert glucose and oxygen into energy, releasing carbon dioxide (CO₂) as a byproduct.
59
Sedimentation
The process by which particles settle to the bottom of a liquid, forming layers of sediment.
60
Fossil Fuels
Natural fuels formed from the remains of ancient organisms (e.g., coal, oil, natural gas).
61

The process of burning fossil fuels, releasing energy, carbon dioxide (CO₂), and water vapor.
62
Extraction
The process of removing fossil fuels from the Earth for human use.
63
Carbon Dioxide (CO₂)
A greenhouse gas produced by respiration, combustion, and decomposition, contributing to global warming.
