Where do decomposers get their energy from?
Dead organisms
100
In the nitrogen cycle, where do animals get their nitrogen?
From plants.
100
Do humans get energy from the Sun?
No. We may get Vitamin D, but we do not get energy. We get our energy from food.
100
What happens when there are different species living in an environment with limited resources?
They compete for available resources.
100
Name one adaptation.
Structure, body process, behavior.
200
What three cycles did we learn about in this chapter?
Carbon, Nitrogen, and Water.
200
What happens to species that cannot adapt?
They become extinct.
200
What is commensalism?
A symbiotic relationship in which one species benefits but the other is not helped or harmed.
200
Why do the fennec, arctic, and gray foxes have different appearances?
They have adapted to different environments.
200
What is an example of a structural adaptation?
Birds develop webbed feet.
300
What happens to energy as it is passed through the levels of the pyramid?
Energy is used by organisms at each level for their own life processes.
300
What is an example of a behavioral adaptation?
Birds fly south for the winter.
300
What is mutualism?
A symbiotic relationship in which both species benefit.
300
One way we can create change, as humans, in our ecosystem?
Knowledge about our problems!
300
Explain how a food chain is related to a food web.
Main Idea: Food chains make up a food web.
400
What species is an example of commensalism? Explain why.
Barnacles on the side of a whale, or a tree plant.
400
When do adaptations occur?
When survival characteristics are passed from one generation to another.
400
In a food web, how might a rat be connected to a fox.
The fox eats the rat for energy.
400
What is a parasite?
An organism that harms another in a symbiotic relationship.
400
What species is an example of mutualism? Explain why.
Bees collect nectar from flowers.
500
What is an example of a body process adaptation?
Animals that hibernate in the winter.
500
What is a producer?
Plants, something that converts energy from the Sun into food. (photosynthesis)
500
How can we avoid permanently damaging our ecosystem?
Recycling, etc.
500
How are photosynthesis and respiration involved in the carbon cycle?
Photosynthesis processes carbon dioxide into oxygen that animals breathe.
500
What is a consumer?
Animals, things that cannot make food from sunlight.
