A “red tide” is dangerous to marine life because it:
Heterotrophic protists must obtain food from their environment. They have developed specialized structures for this purpose. 21.3 The Ecology Of Protists Answer Key
A harmful algal bloom (HAB) is a rapid overgrowth of certain algae or dinoflagellates that produces toxins or depletes oxygen. Causes include excess nutrients (fertilizer runoff, sewage) and warm temperatures. A “red tide” is dangerous to marine life
HABs create dead zones, disrupt food webs, and cause mass mortality. Many protists are , meaning they use light
: This protist lives in the digestive system of termites , helping them digest the cellulose in wood, which the termites cannot do on their own.
Many protists are , meaning they use light to create their own food through photosynthesis.
They deplete oxygen and nutrients, killing fish and other marine life. Temporarily stores and digests food. What is a gullet?
