All Flashcards
Define ectotherm.
An animal that relies on external sources of heat to regulate its body temperature.
What is coral bleaching?
The expulsion of zooxanthellae from coral tissue, causing the coral to turn white.
Define zooxanthellae.
Algae that live symbiotically within coral tissues.
What is albedo?
The measure of how much light that hits a surface is reflected without being absorbed.
Define coral polyp.
Tiny, individual animals that make up a coral colony.
What is a symbiotic relationship?
A close and long-term biological interaction between two different biological organisms.
Cause and effect of increased ocean temperature on coral?
Cause: Increased ocean temperature. Effect: Coral bleaching and potential death of coral reefs.
Cause and effect of melting sea ice?
Cause: Rising global temperatures. Effect: Sea-level rise, habitat loss, and reduced albedo.
Cause and effect of ocean warming on marine ectotherms?
Cause: Increased ocean temperature. Effect: Metabolic stress, reduced reproduction, and potential death.
