b. Plant more trees along the rivers.
c. Stop traveling by airplane.

Set up trash cans along the river
What sphere of Earth includes all water on Earth?
Hydrosphere
Explain how the Water Cycle works.
1) Collection - water is gathered into a resovoir
2) Evaporation - water is heated by the sun and turns to gas (water vapor) and rises into the atmosphere
3) Condensation - water vapor rises into the atmosphere and cools, turns to water droplets and form clouds
4) Precipitation - water droplets become too heavy for cloud and precipitation falls
What gas to plants give us and what gas do we provide to plants?
Plants give us Oxygen and we give plants CO2 (Carbon dioxide)
In a desert habitat, it is common to find lizards and snakes laying in the sunlight. Why do they do this?
Helps them to regulate their body temperature
Which sphere of Earth is made up of gases?
The Atmosphere
What sphere of Earth refers to all life on Earth?
Biosphere
A student named Ben thinks that only plants can store energy. Is he right or wrong? Explain why.
A tropical plant relies on monkeys to transport its seeds to new locations. This is an example of:
a. Pollination
b. Interdependence
c. Competition
d. Food web
Interdependence
What do owl's eye colors mean? (yellow, orange, and black)
Yellow - daytime hunters
Orange - dawn/dusk hunters
Black - nighttime hunters
1. Throw away trash
2. Recycle
3. Turn off lights
What sphere of Earth refers to land on Earth?
Geosphere or Lithosphere!
Why are there not many decomposers in the tundra habitat?
Why are plants that grow in the ocean most often found in shallow water?
There is more sunlight in shallow water
What does a food chain show?
What eats what in an ecosystem
Humans pollute a lake with oil and waste. How might this affect the water cycle?
The water might not be able to evaporate as fast, slowing the water cycle
What are 3 biotic factors?
1. Bear
2. Fish
3. Crab
A teacher asks her students how a caterpillar finds the energy to turn into a butterfly. George answers, “Plants.” Hannah answers, “The Sun.” Who is correct?
Both! A caterpillar will eat a lot of plant matter to obtain energy. The plants obtain their energy from the Sun during photosynthesis. Simply, the energy from the Sun is transferred to the plant and to the caterpillar when it eats the plant.
Describe the stages of the plant life cycle in detail.
Seed dispersal - seeds are scattered by wind, water, and animals
Germination - seeds receive water, sunlight, and nutrients they need to begin growing
Mature Plant - the adult plant is able to make its own food through photosynthesis
Pollination - adult plants gets pollinated and seeds become dispersed again
What kind of model would be best to describe competition and interdependence in the ocean?
a) Food chain
b) Food web
c) Food pyramid
d) Ecocolumn
Food web
How might an ecosystem be impacted by deforestation?
Animals could lose their homes
What are 3 examples of 3 abiotic factors?
1. Stone
2. Air
3. Sand
How would water from a lake create a pond on a mountainside? List the steps from first to last.
evaporation [water turns into a gas] ➔ condensation [gas turns into water as clouds] ➔ precipitation [water falls back to Earth]➔ collection [water forms in the pond on the side of the mountain])
