![Page 1: What animals do to survive: 1. Feeding:. Herbivore = eats plants Carnivore = eats animals Omnivore = eats plants and animals Detritivore = feed on decaying.](https://reader036.fdocuments.us/reader036/viewer/2022081419/56649e9e5503460f94b9f76c/html5/thumbnails/1.jpg)
What animals do to survive:
1. Feeding:
![Page 2: What animals do to survive: 1. Feeding:. Herbivore = eats plants Carnivore = eats animals Omnivore = eats plants and animals Detritivore = feed on decaying.](https://reader036.fdocuments.us/reader036/viewer/2022081419/56649e9e5503460f94b9f76c/html5/thumbnails/2.jpg)
Herbivore = eats plantsCarnivore = eats animalsOmnivore = eats plants and animalsDetritivore = feed on decaying organic materialFilter Feeders = aquatic animals that strain food from waterParasites = lives in or on another organism (symbiotic relationship)

2. Respiration:
Take in O2 and give off CO2 Use: Lungs, gills, through skin, simple diffusion

3. Circulation:Very small animals rely on diffusionLarger animals have circulatory system

4. Excretion:
Remove waste products from the body.Specialized organs like kidneys in complex animals.

5. Response to stimuli:Receptor cells pick up stimuli = sound, light, external stimuli

6. Movement:Most animals are motile (can move)Muscles usually work with a skeleton

7. Reproduction:Most reproduce sexually = genetic diversity
Many invertebrates can also reproduce asexually = to increase their numbers rapidly
