Question

a type of photosynthetic algae that corals have a symbiotic relationship with.
a process where coral is stressed and expels its symbionts which makes it appear to turn white.
a certain range of environmental conditions under which organisms can perform their life activities.
water that melts from glaciers and run off the land and into the oceans.
frozen freshwater that sits on top of landmasses.
in the ocean as liquid water warms, it takes up a larger volume.
seawater is slightly basic on the ph scale, however as it absorbs co2, it causes the water to acidify.
:: background extinction :: biodegradable :: biological accumulation :: biological magnification :: climate change
:: coral bleaching :: eutrophication :: glacial ice :: greenhouse gases :: habitat fragmentation
:: harmful algal blooms :: invasive species :: marine debris :: mass extinction :: meltwater :: ocean acidification
:: ocean - based sources :: overexploitation :: point source pollution :: pollutant :: range of tolerance (environmental)

Explanation:

1. Corals have a symbiotic relationship with zooxanthellae, a type of photosynthetic algae.
2. Coral bleaching is the process where stressed coral expels its symbionts and turns white.
3. The range of tolerance (environmental) is the certain range of environmental conditions under which organisms can perform their life - activities.
4. Meltwater is water that melts from glaciers and runs off the land into the oceans.
5. Glacial ice is frozen freshwater that sits on top of landmasses.
6. Thermal expansion occurs in the ocean as liquid water warms and takes up a larger volume.
7. Ocean acidification is when seawater, which is slightly basic on the pH scale, becomes more acidic as it absorbs CO2.

Answer:

1. Zooxanthellae
2. Coral Bleaching
3. Range of Tolerance (environmental)
4. Meltwater
5. Glacial Ice
6. Thermal Expansion
7. Ocean Acidification
