How does the Earth recycle? (not human recycling)
“I don’t know anything.” is not an acceptable answer.
Use complete sentences.
Evidence
After listening to the PowerPoint lecture, come back here and list evidence
to explain why your answer to the above question is or is not a good
answer. You may also use other outside sources to help you respond.
Draw a picture showing the ways recycling in an ecosystem is limited.

water cycle
Process
evaporation
condensation
precipitation
Recycling in Ecosystems
Information
- a continuous process where water moves from the Earth’s surface,
to the atmosphere, and back again
1. evaporation  2. condensation  3. precipitation
- Liquid water absorbs energy and changes to water vapor.
- Water vapor changes to a liquid - droplets collect around
dust particles to form clouds.
- Water vapor condenses. Clouds grow “heavy.” Water falls back
to Earth.
Nitrogen cycle
dispersal
- organisms moving from one place to another
How?
1. Wind/water - Wind and water transport seeds, spores, and smaller
organisms
2. Other moving things - People move plants and animals.
native species
- organisms that naturally live in an area Example: Evergreen trees
exotic species
- (AKA - invasive species) species that are transported to a new area
Limits
Summary:
Examples: opossum, scotch broom, English ivy
1. Physical barriers - water, mountains, deserts - hard to cross
2. Competition - New organism has to find niche to survive.
3. Climate - Temperature determines if a species can survive.
