3. Kingdom Fungi multicellular eukaryotic Nutrients from absorbing foods decompose dead organisms; do NOT perform photosynthesis do not move Ex: mushrooms, puff balls; yeast, molds 1
4. Kingdom Plantae multicellular eukaryotic autotrophs/photosynthetic 3
5. Kingdom Animalia (1.5 million in category) multicellular eukaryotic Nutrients obtained from ingestion heterotrophs have organelles including a nucleus, but no chloroplasts or cell walls they move 4
a) invertebrates – no backbone 97% of all animal species Ex: worms, insects, spiders, mollusks 5
b) vertebrates (3% in animalia)– backbone Ex: snakes, turtles, frogs, humans 6
C. Aquatic Life Organisms within the river are classified by: Structure how they obtain their food 8
Dominate river organisms: 1. Algae - autotrophs **since algae makes its own food it is considered the base of many food chains. 9
Algae 10
3. Animal like Protists – eat sediments containing bacteria 12
4. invertebrates – insects, mollusks (clam like), and worms in the substrate 13
Insects 14
Mollusks 15
Worms 16
most feed on algae and plants Therefore, PRIMARY consumers a) grazers – grazes on algae; Ex: snails 17
b. shredders – shreds and eats plant material, such as tree leaves Ex: stone flies, crane fly 18
c. Collectors – eat the crumbs from the shredders; gathers or filters from water Ex: clam, caddis fly 19
Predators – feeds on other animals; Ex: water beetles 20
Parasites – nourishment from a host Ex: leech 21
5. Insects adults – three body parts • Head • thoracic region (legs and wings are jointed ) • abdomen (organ location) 22
Metamorphosis –change of insect from egg to an adult 2 types: * incomplete metamorphosis - ENA 23
● Eggs ● Nymph - some look like the adult - molts sheds exoskeleton - develops directly into the adult - no cocoon - no wings , can’t reproduce ● Adult - wings; mates; return to lay eggs -main purpose is to reproduce 24
examples: damsel fly dragonfly 25
* complete metamorphosis (ELPA) ● Eggs ● Larva - soft bodies - look nothing like the adult ● Pupa (cocoon) - inactive, not feeding ● Adult • emerges from cocoon to mate • – wings 28
6. Vertebrates a. Amphibians: smooth moist skin must use water for reproduction no claws on feet breath through skin and lungs Ex: frogs, toads, newts, salamanders 30
b. Reptiles dry scaly skin if feet will have claws lay eggs for reproduction lungs Ex: snakes, lizards, turtles 32
c. fish some primary consumers of algae some are strictly predators d. Birds e. Mammals hair, fur, nourish young with milk 33
