Which of the following factors are Biotic?
Which pictures represent Abiotic factors?
What will happen to the prey population if the predator population increases?
Well, of course if more predators come in, the size of the prey population will go down!
Not much really. This is Nature’s way. All part of the circle of life.
Lets see, with predators coming in, the size of the prey population is bound to go up.
All the prey members will pack up and move to Florida
What will happen to the predator population if the prey population goes down?
The predators decide to become vegans and eat vegetables.
The predators start howling at the moon
They get confused and begin to eat their own young.
The predators will move out in search of other prey.

When two or more species use the same resources, they may fight for access to the resource. They will fight for the right to use the water, the land or whatever they are both trying to use. Only the strong will survive and be able to use the resource. Loser? So long........

The Sun
The Water Cycle
Living things that take energy from the environment and store it in sugar molecules.
Parasites
Autotrophs
Heterotrophs
Decomposers
Plants. Absorbs solar energy from the sun and puts it into sugar molecules
Photosynthetic Heterotrophs
Chemosynthetic Heterotrophs
Photosynthetic Autotrophs
Chemosynthetic Autotrophs
This organism cannot reach the sun. It takes energy from the breakdown of nitrates and puts it in sugar.

Chemosynthetic Autotrophs
Chemosynthetic Heterotrophs
Photosynthetic Autotrophs
Where would you find this fish?
These fish are found down deep around the thermal vents. Here the chemosynthetic autotrophs begin the food chain.
These unique fish are found around the coast of Hawaii. Here they feed on the smaller fish that live in and around the coral reef.
These fish feed upon the photosynthetic autotrophs that exist at the surface of the water. They are a prized commodity in Asian culture.
These fish are only found in areas of extremely low pressure, like mountain streams.
These living things must eat in order to get the energy into their body.
Heterotrophs
Photosynthetic Autotrophs

All energy comes from the sun. Which example below illustrates how that energy gets to us?
Food Chain
Food Cycle
Energy Pyramid
Trophic Level Pyramid
Each step in the food chain is called a :
Trophic Level
Trophic Zone
Pyramidal Step
Trophic Step
In real life, food chains overlap. Many different consumers may feed from the same producer! Many secondary consumers may feed from the same Primary Consumer. To illustrate that , we use the following model.
Food Web
A food chain network
A Food Cooperative
A Trophic Anex
Which one is the primary producer?
Grass
Grasshopper
Frog
Snake
Eagle
Which one is the Primary Consumer?
Grass
Grasshopper
Frog
Snake
Eagle
Which one is the Secondary Consumer?
Grass
Grasshopper
Frog
Snake
Eagle
Which one is the Tertiary Consumer?

Eagle
Which one is the Apex Predator?
Grass
Grasshopper
Frog
Snake
Eagle
In this pyramid, each level represents the amount of energy that is available to that trophic level.

Biomass Pyramid
Why is it necessary for nutrients to be cycled through the biosphere?
There is only a certain amount that humans are allowed to use per year.
Nature does not recycle!
Oh yes I remember, its easier for nature to recycle than to create new stuff.
Well, if nature did not recycle the nutrients, we would run out!
The natural process by which water is continuously cycled through the biosphere
Water Cycle
Hydro Cycle
Aqua Cycle
The Carbon Cycle
Water falling from the sky. It may be rain, snow, or hail
Precipitation
Evaporation
Condensation
Transpiration
Run Off
Water changes into a gas, and rises up into the atmosphere.
Precipitation
Evaporation
Condensation
Transpiration
Run Off
in the atmosphere, water vapor cools, and changes back into liquid water.
Precipitation
Evaporation
Condensation
Transpiration
Run Off
Water also escapes from the leaves of plants. This water changes into a gas also and goes up into the atmosphere.
Precipitation
Evaporation
Condensation
Transpiration
Run Off
Water hits the ground and begins to move towards a water source, like the ocean.
Precipitation
Evaporation
Condensation
Transpiration
Run Off
Rain water begins to be absorbed by the soil. It moves on downward until it hits an underground reservoir
Oh yes, this is called Run Off
This is Evaporation
This is a very good thing called Recharging the Aquifer!
This is Transpiration
Describe the Oxygen - Carbon dioxide cycle
As the air is blowing against the leaves, The Oxygen is filtered out and Carbon dioxide is put back into air.
Plants use Carbon dioxide and water to make sugar. Oxygen is given off as a waste product.
Carbon dioxide is filtered through the leaves and Water and Oxygen are put back into the air.
Plants use Carbon dioxide and Oxygen to make sugar. Water is given off as a waste product.
Why is the Nitrogen Cycle so important?
Nitrogen is used to slow down the Oxygen that we take in.
Nitrogen is a necessary raw material used for making proteins.
Nitrogen is a universal buffer. It takes toxins out of the body.
Nitrogen helps in the bodies immune system to get rid of bacterial
How much of our atmosphere is actually Nitrogen Gas?
100%
78%
.03%
50%
Why must Nitrogen go through a Biochemical cycle before entering our food chain?
Living things tend to absorb too much gaseous Nitrogen
No living thing has the ability to use Atmospheric Nitrogen.
Straight Nitrogen would cause cell death
Nitrogen gas would slow down Cell Respiration.
As the air circulates around the roots, bacteria change the gaseous nitrogen into nitrates during a process called:
Modulation
Defecation
Nitrogen Fixation
Ammonification
When an animal dies, what happens to its proteins?
Nitrogen bonds with water and is absorbed into the soil.
Proteins are changed into sugars to be used as food
Proteins release their nitrogen back into the atmosphere
The proteins are changed into ammonia. Bacteria convert this into nitrates
What is the major use of Phosphorus in the body?
Creation of blood plasma
Protein and Nervous tissue
Bones and Teeth
Used to illuminate the interior of the body
The cycling of nutrients in the biosphere involves both matter in living organisms and physical processes found in the environment such as weathering.
Biogeochemical cycle?
Water Cycle
Phygeochemical cycle
Elemental C;ycle
