Energy Pyramids
How much energy is kept between each trophic level?
10%
This is the number of hydrogen atoms in a water molecule.
2
How do we calculate the speed of an object?
Speed= distance divided by time
What does the muscular system do?
Supports and helps the body with movement
If the sun, moon, and Earth are aligned is it a spring or neap tide?
Spring
What is the ultimate source of energy?
The sun
This is the number of oxygen atoms in a water molecule.

What is newton's first law of motion?
An object in motion stays in motion and an object at rest stays at rest.
Where does digestion begin?
The mouth
If the northern hemisphere is at its furthest point to the sun and is facing away from the sun, what season is it?
Winter
Who eats a secondary consumer?
Tertiary consumer
This is the chemical formula for water.
H20
What is newton's second law of motion?
force= mass x acceleration
The urinary systems two jobs include:
Filters blood and produces urine.
If the northern hemisphere is at its furthest point to the sun and is facing towards the sun, what season is it?
Summer
What happens if the secondary consumer is removed from a food chain?
The tertiary consumer has nothing to eat.
This property of water demonstrates the attraction of one water molecule to another.
Cohesion
A car with a mass of 1,200 kg accelerates at a rate of 3 m/s².
What is the net force acting on the car?
3600 N
What two systems work together for movement?
Skeletal and muscular
If the northern hemisphere is at its closest point to the sun and is facing away from the sun, what season is it?
Spring
If the producers can not perform photosynthesis what happens to the entire food chain?
It collapses
This property of water demonstrates the attraction of one water molecule to another object.
Adhesion
Using Newton's second law, determine the acceleration of the car. A car’s engine uses a force of 100 N and the car weighs 900 kg.
a= 0.11m/s^2
What does the endocrine system do?
Produces hormones to help body processes
If the northern hemisphere is at its closest point to the sun and is facing towards the sun, what season is it?
Autumn/fall
