The flow of energy between organisms can be shown using a pyramid shape because:
There is more energy at the top than at the bottom
There is more energy at the bottom than at the top
Energy is lost as you move up the pyramid
Both B and C
Why are animals important to the process of photosynthesis?
Animals eat plants, which makes space for more plants to grow.
Animals digest food, which provides the starting materials for photosynthesis.
Animals release carbon dioxide, which provides the starting materials for photosynthesis.
Animals produce energy in the form of heat, which is necessary for photosynthesis to occur.
How do organisms get the energy they need?
Plants get energy from fertilizers, and animals get energy by drinking water.
Plants get energy from glucose produced in the soil, and animals get energy directly from the sunlight.
Plants do not require energy because they do not move, and animals get energy by performing exercise.
Plants break down the glucose produced in photosynthesis, and animals get energy from eating other organisms.
What is an organism called that feeds on another organism?
consumer
scavenger
producer
decomposer
If there were no decomposers, which of the following would most likely happen?
Animals would start performing photosynthesis.
Plants and animals would remain living for a longer period of time.
The amount of dead animal matter would decrease.
Plants would lack nutrients they receive from decomposers.
An organism that return matter from dead plants and animals back to the soil is called a ____________?
carnivore
decomposer
herbivore
omnivore
Which of the following is the correct equation for PHOTOSYNTHESIS?
CO2 + light + H2O --> O2 + Sugar
CO2 + sugar + H2O --> O2 + light
O2 + light + H2O --> CO2 + Sugar
CO2 + O2 + H2O --> Light+ Sugar
Which of the following is the correct equation for CELLULAR RESPIRATION?
CO2 + energy + H2O --> O2 + Sugar
CO2 + sugar + H2O --> O2 + light
O2 + Sugar--> CO2 + energy + H2O
CO2 + O2 + H2O --> energy+ Sugar
What are the products of Cellular Respiration?
Carbon dioxide, energy and water
Carbon dioxide and oxygen
Glucose and oxygen
Glucose, energy and water
Which of the following go through the chemical reaction of cellular respiration?
Humans
Plants
Animals
All of the Above
Cellular respiration and photosynthesis are:
The same reactions
Opposite reactions
Unrelated reactions
Only done in plants, algae, and many microorganisms
How are photosynthesis and cellular respiration connected?
Photosynthesis is how plants, algae, and many microorganisms get their food and cellular respiration is how they turn that food into energy.
Cellular respiration is how plants, algae, and many microorganisms get their food and photosynthesis is how they turn that food into energy.
Photosynthesis and cellular respiration are the processes by which plants, algae, and many microorganisms make their own food.
Photosynthesis and cellular respiration are unrelated.
Which of these experiments would provide evidence that plants conduct cellular respiration?
Place a plant in water in a sealed aquarium under a lamp, and measure the amount of water used.
Place a plant in a vacuum-sealed aquarium under a lamp, and measure the amount of oxygen produced.
Place a plant in water with dissolved nitrogen, and measure the amount of nitrogen absorbed by the plant.
Place a plant in a sealed aquarium filled with oxygen in the dark, and measure the amount of oxygen used.

What is the purpose of cellular respiration?
to make food
to release energy from food
to take in food
to release oxygen
In what stage of the Water Cycle does water fall back to the Earth? In the form of rain, snow, sleet, or hail.
