Size range from 2 micrometers (heterotrophic flagellates protists) up to several meters jellyfish. Primary consumers/carnivores: feed primarily on other zooplanktons (animals) Detrivrores: feed primarily on dead organic matter (detritus) Calcareous shell composed of a series of chambers; calcareous ooze sediments: 30 micrometer to 1-2 millimeter, most abundant 40on 40os: radiolarians b. i. Spherical cells with silica capsule; 50 micrometer to several millimeter; siliceous ooze sediment, cold water and deep sea c. Feed on diatoms: animalia, arthropods (crustaceans) a. i. Most abundant and widely distributed animal in the world a. ii. 1. a. ii. 2. a. ii. 3. a. ii. 4. Most have exoskeleton of: caco3 (calcium carbonate, chitin (organic material, sio2. Corals: vary in size, calcium carbonate exoskeleton, solitary or colonial, feed at night, ahermatypic corals, hermatypic corals zooxanthellae. Nutrient rich = algal blooms block light. Example : polychaetes (many bristle: most important marine annelids, include infauna/epifauna, detritus feeders, size from 1-15cm, tubeworms. Sessile benthos: live on or in the substrate.
