How do plants get their energy?
Through a process called Photosynthesis.
What is the pigment that captures the energy of sunlight?
chlorophyll
True / False
Animals depend on energy from the sun for their food?
True
What is the original source of energy for organisms in a food chain?
sunlight
What is an ecosystem?
All the living and nonliving things that interact in an area
What are two different types of decomposer?
Fungi & Bacteria
Plants are able to make their own food and energy. Animals must eat other living things for energy.
Which plant part is mainly responsible for capturing sunlight and carrying out photosynthesis?
the leaves
This model best demonstrates what cycle?
The oxygen-carbon dioxide cycle
What is a food chain?
A path showing energy flowing from one living thing to another
Name some physical characteristics of an environment.
Oxygen, carbon dioxide, temperature, weather, soil
In what way doesw matter move in an ecosystem?
Matter moves in cycles
What are the three main things plants need to grow?
sunlight,
air / carbon dioxide
water
What role do roots play in making food for a plant?
Roots take in water.
Animals need food for many reasons. Name at least 2 things that food provides for animals?
1. to grow
2. to move
3. to keep warm
4. to repair
*Other answers may be acceptable, Judge choice*
What do decomposers do?
Break down dead organisms or the wastes of living things
What does this picture of spider monkeys represent in an ecosystem?
A population
How do animals get the nitrogen they need?
They eat plants or other animals that eat plants.
You are growing plants in a water that includes nutrients (no soil). What is the name of this method of growing plants?
Hydroponics
Which is the product of photosynthesis that plants use?
water carbon dioxide oxygen
chlorophyll sugar sunlight
sugar
Your friend says that animals do not depend on energy from the sun to make their food. Do you agree? Why or why not?
I would disagree because animals either eat plants or other animals that eat plants.
(all food was once energy from the sun)
What does a food web show?
The different paths or food chains that energy follows as it moves through an environment
Which or the following does NOT describe a healthy ecosystem?
A. All species meet their needs
B. A stable physical environment
C. Includes invasive species
D. Includes many species of different types.
c. Includes invasive species
How do plants and animals interact in the carbon-dioxide oxygen cycle?
Plants take in carbon dioxide and give off oxygen, while animals breathe in oxygen and give off carbon dioxide.
Answers may vary.
*Judge decision*
Plants use the products made during photosynthesis to carry out their basic functions. Where does the energy to make these products come from?
Sunlight
What are 3 physical characteristics of an environment?
Temperature, oxygen, soil, water, weather, climate
Additional answers could vary, Judge's decision.
What would happen to this food web is the mouse population decreased?
The entire food web would be affected
1. What is an invasive species?
2. Give 2 examples of US invasive species we learned in class.
An organism that does not belong in a certain place and harms the environment
Kudzu and red imported fire ants
Describe the nitrogen cycle, starting with soil.
Plants take in nitrogen from the soil. Animals take in nitrogen from the air or plants. When plants and animals dies, decomposers release the nitrogen to the soil and air.
