Abiotic and Biotic Factors
A factor of an ecosystem that is nonliving
what is an abiotic factor?
In a food web, these organisms use the sun’s energy to make their own food.
What are producers?
This is the main source of energy for all life on Earth.
What is the sun?
This term describes an ecosystem where plants, animals, and other organisms interact in a balanced way.
What is a healthy ecosystem?
A factor of an ecosystem that is living
What is a biotic factor
Mushrooms, bacteria, earthworms, and beetles are all what?
What are decomposers?
Energy flows in a food web from one organism to another when this happens.
What is eat?
This activity, when done responsibly, can improve the health of ecosystems by reducing waste and using fewer resources.
What is recycling?
These organisms use sunlight to make their own food through photosynthesis.
What are plants?
If the population of predators increase, what would happen to the prey?
what is decrease?
this type of organism is always the first to receive energy from the Sun.

What is pollution?
Temperature, sunlight, and water are all examples of these factors.
What is abiotic
A hawk eats a snake, which ate a mouse. The hawk is this type of consumer.
What is a tertiary consumer?
This type of consumer eats plants and gets energy directly from producers.
This type of relationship, like between bees and flowers, helps both species survive and thrive in a healthy ecosystem.
What is mutualism?
Give an example of how a biotic factor interacts with an abiotic factor for survival in an ecosystem.
Correct!
If a top predator, like a wolf, is removed from a food web, this effect could happen to its prey.
What is overpopulation?
Only about this percentage of energy is passed from one level of the food web to the next.
what is 10%
A species that moves into a new area and harms the native ecosystem is called this.
What are invasive species?
