“I don’t know anything.” is not an acceptable answer.
Use complete sentences.
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.

Recycling in Ecosystems
water cycle - a continuous process where water moves from the Earth’s surface, to the atmosphere, and back again
Process 1. evaporation 2. condensation 3. precipitation- Liquid water absorbs energy and changes to water vapor.
Summary:
- 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.
evaporation
condensation
precipitation
Nitrogen cycle
- organisms moving from one place to another
How?
dispersal
1. Wind/water - Wind and water transport seeds, spores, and smaller organisms
native species - organisms that naturally live in an area Example: Evergreen trees
2. Other moving things - People move plants and animals.
exotic species - (AKA - invasive species) species that are transported to a new area
Examples: opossum, scotch broom, English ivyLimits 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.
