1. Matter and Energy in the Environment
Chapter 5

2. Bellringer. How do the flamingos survive?
How do the flamingos depend on the nonliving things in the photo on page 704?
How might the flamingos interact with the living things in their environment?

3. What do you think? Agree or Disagree. Why?
The air you breathe is mostly oxygen.
Living things are made of mostly water.

4. Lesson 1: Abiotic Factors Vocabulary
Ecosystem: all the living things and nonliving things in a given area
Biotic Factor: the living things in an ecosystem
Abiotic Factor: the nonliving things in an ecosystem
Climate: average weather conditions in an area over time
Atmosphere: the layer of gases that surrounds the Earth.
System: a set of things working together as parts of a mechanism or an interconnecting network

5. List Abiotic and Biotic Factors in appropriate columns
ABIOTIC FACTORS:
Sunlight
Wind
Air
Climate
Temperature
Water
Atmosphere
Soil
Rocks
Mud
BIOTIC FACTORS:
Humans
Animals
Bacteria
Cells
Fungi
Insects
Trees
Plants
Flowers

6. What is an ecosystem? Vary in size: forest, lake, under a rock
All organisms need biotic and abiotic factors in order to survive
Abiotic and Biotic factors depend on one another. If one part is disturbed the others can be affected

7. Abiotic Factors The Sun Climate Temperature
Source of almost all energy on Earth
Provides Warmth and Light
Affects Climate and Temperature
Conditions include: temperature, moisture, and wind.
Influences where organisms live
Influences where organisms can survive
Temps on Earth vary

8. Abiotic Factors Continued…
Atmosphere
Water
Soil
Made of rock, water, air, minerals and remains of living things.
Home for many organisms
Bacteria breaks down dead plants/animals returning nutrients to soil
Insects make tunnels allowing air and water to move through
All life on Earth requires water for life processes such as growing/reproduces
Living things are about 70% water
All ecosystems must contain water to support life
Mostly made of nitrogen/oxygen
Provides living things with oxygen and protects from harmful rays from the Sun
