Kingdom Animalia Invertebrates

General Description:
Animals: multicellular, eukaryotic, heterotrophic, cells lack cell walls, most reproduce sexually
Sponges: Spend most of life on ocean floor, feed by filtering water (containing small organisms and nutrients) through their body, reproduce sexually and asexually    
Cnidarians: Aquatic animals with a radial body shape (named for stinging cells), have two basic body forms: the polyp and medusa, produce sexually and asexually

Defining Characteristics:

• Being generally motile (being able to move voluntarily)
• Hetertrophs
• Fur (some not all)

Evolutionary Adaptations:
- sexual reproduction- genetic variation
- different animals show different adaptations- species of frog that doesn't have lungs
- internal digestive chamber



Ecological Importance:
-earth's major diversity
-animals produce carbon dioxide for plants
-help maintain food chain


Example: 2.Earthworms Lumbricus terrestris
4. habitat- top soil or deep soil
niche-  aerate soil, feed on leaves, fertilize soil with waste, source of food for birds
5.-do not have eyes
-detect light with light detective organs
-have no teeth
-earthworms have no hearts
-excellent source of protein
