1. Explain how carrying capacities can vary over time.
2. If a population is below its carrying capacity, how will it respond? Why?
3. If a population is constant, what can be said for the birth and death rates?

3/11 Objective
ELEMENTS!
Let’s talk about a water cycle!
What comes
to mind when I
say the water
cycle?
Matter, made of elements move through the ecosystem.
Key Point #1: Matter is anything that has mass and takes up space
Remember: Matter is not created nor destroyed. It is RECYCLED!
WATER CYCLE
TRANSPIRATION
Transpiration
Key Point #2: Transpiration is water passing from a plant to the atmosphere.
Evaporation from a plant!
TRANSPIRATION
EVAPORATION
Evaporation
Key Point #3: Evaporation is water turning from a liquid to a GAS!
From a body of water
There is water present in both plants and bodies of water (rivers, lakes, oceans).
a. Water leaves a plant and enters the atmosphere through the process of:
TRANSPIRATION
b. Water leaves a body of water and enters the atmosphere through the process of:
EVAPORATION
Do we have it?!
TRANSPIRATION
EVAPORATION
CONDENSATION CONDENSATION
Condensation
Key Point #4: Condensation is water vapor into liquid
Clouds!
TRANSPIRATION
EVAPORATION
CONDENSATION CONDENSATIONPRECIPITATION
Precipitation
Key Point #5: Precipitation is water that falls from the clouds
Snow, hail, freezing rain, and rain
TRANSPIRATION
EVAPORATION

RUN-OFF
COLLECTION
GROUNDWATER
Key Point #6: Water runs off and will collect in lakes, ponds, and oceans.
Ground water is water held under the soil

How does water connect organisms to their
environment?
Revisiting the objective:
NITROGEN CYCLE
Nitrogen Cycle
There is A LOTof ________ in the air, but plants and animals CAN’T use it!
NITROGEN
Nitrogen Cycle
Key Point #7: Fix: bacteria
changes nitrogen into ammonia
Nitrogen Fixation
Key Point #8: Plants and animals release nitrogen when they die.
RECYCLING!
Plants and animals die and return nitrogen
back to the soil.
This the nitrogen
that needs to be
“fixed”.
What is the impact of removing ALL of the bacteria from the world?
Turn and Talk
Answer the following questions on a half sheet of paper for page 29!
1. After millions of years, what do decaying plants and animals turn into?
2. What process is very similar to evaporation?
3. When water from lakes goes into the air, what process is this called?
4. What form does nitrogen need to be in order for plants to use it?
5. When it snows, what part of the water cycle is this?
6. What part of the water cycle is it when water leaves plants and goes into the air as water vapor?
7. What organisms collect nitrogen in the air and change it into a form plants can use?
8. How do animals get their nitrogen?
9. When water vapor changes into clouds, what process is this called?
10. Name two different types of precipitation.

CARBON CYCLE
Photosynthesis
• Key Point #9:
Photosynthesis produces
carbs• (CO2 is removed from
the air, thanks plants)
Respiration

Combustion
Key Point #12: Fossil fuels are burned and CO2 is released in COMBUSTION
Let’s earn these class points!
Show me what ya know!
Photosynthesis
Burning fossil fuels and releasing CO2 back in the air
Define Combustion
Respiration
Kobe uses sugar to keep going during a big game. He
breathes out CO2.
DECOMPOSITION
Water taken from plants like evaporation
Define Transpiration
This is the process where water turns from
a liquid into a gas. Evaporation
N2 is changed to a usable form of nitrogen during:
Nitrogen Fixation
Snow, sleet, hail and rain are examples of this process.
Precipitation
