18.1 Abiotic Factors
7. • Ecosystem – all the living and
nonliving things in a given area.
1. What makes up an ecosystem?
• An ecosystem
can be a pond,
a desert, an
ocean, a forest,
or your
neighborhood.

11. 1. Air (Atmosphere)
• Provides living things with
Oxygen
– Atmosphere = 78% N2, 21%O2
• Protects them from certain
harmful rays from the sun
Abiotic Factors that affect living things:
12. 2. Water
• All life requires water
• Organisms are made mostly of water
• Need water for important life processes
(growing & reproducing)
13. 3. Sunlight
• Source of almost all energy on Earth
• Provided warmth & light
• Plants use sunlight to make food
14. 4. Soil
• Provides water and nutrients for plants
• Home for many organisms
• Soil is made up of bits
of rocks, water, air,
minerals, and the
remains of once-living
things.
16. 6. Climate
• Influences where organisms can live
• Climate describes
average weather
conditions in an
area over time.
• A climate’s
weather conditions
include temperature,
moisture, and wind.
17. • Ecosystems include all
the biotic and abiotic
factors in an area.
• Biotic factors are the
living things in
ecosystems.
18. • Abiotic factors are the nonliving
things in ecosystems, including
water, sunlight, temperature, climate,
air, and soil.
