Photosynthesis
What do plants need for photosynthesis?
Water, sunlight, carbon dioxide
What is a food chain?

Define producer.
An organism that makes its own food
How does energy flow in an ecosystem?
From producers to consumers
What do plants need to grow?

What is the role of decomposers?
To break down dead organisms
Name a factor that affects plant growth.
Soil type, temperature, water availability
What do plants release during photosynthesis?
Oxygen
What is the difference between a food chain and a food web?
A food web is the interacting and overlapping of all the food chains in an ecosystem.
Give an example of a decomposer.

How do organisms interact in a food web?
They depend on each other for food
How do plants absorb nutrients?
Through roots
Why is photosynthesis important for ecosystems?
It provides energy for consumers
What happens if one organism is removed from a food chain?
It can disrupt the balance of the ecosystem
What role do producers play in an ecosystem?
They provide energy for all organisms
Describe how energy is transferred in a food chain.
From producers to consumers to decomposers
Describe an experiment to test plant growth.
Compare growth with different light sources
