What is a producer?
What is a producer?
A producer is an organism that makes its own food.
Where does energy enter most ecosystems from?
Energy enters as sunlight.
What two main products do plants make during photosynthesis?
Sugar and oxygen.
Is a rock living or nonliving?
Nonliving
What is matter?
Matter is anything that takes up space and has weight.
Give one example of a producer found in most ecosystems.
A plant, such as a tree, grass, or algae.
Explain how energy flows from the sun to an animal in three steps.
Sunlight → producers make food (plants) → animals eat the plants and get energy.
What two raw materials (inputs) do plants need for photosynthesis?
Carbon dioxide (from air) and water.
Name one feature that all living things share.
They grow, reproduce, use energy, or respond to their environment.
Through which part of the plant does water enter from the soil?
The roots
What do producers need from the air to make food?
Carbon dioxide.
What did Jan van Helmont conclude in his experiment about where tree matter comes from?
He concluded that trees do not get the matter they use for growth from soil.
Write a simple sentence that explains why sunlight is important for photosynthesis.
Sunlight provides the energy that plants use to make sugar during photosynthesis.
Give two examples of living things you would find in a garden.
Plants, insects, worms, or birds.
Why are producers important to animals in an ecosystem?
Producers make food (and oxygen) that animals use for energy and survival.
Why are producers important to the whole ecosystem?
They make the first food and provide energy and oxygen for others.
How does the sugar made in photosynthesis help a plant when it cannot perform photosynthesis?
The plant can convert sugar to starch and store it for energy when photosynthesis is not happening.
How can you tell the difference between a living seed and a nonliving rock? Give one test or observation.
Put both in soil and water—if the seed sprouts and grows, it is living; the rock will not grow.
Name two things producers release or provide during photosynthesis that other organisms need.
Sugar (food) and oxygen.
Where in the plant does most photosynthesis happen?
In the leaves.
