Relationships in Ecosystems
A close and often long-term relationship between two different living organisms.
What is symbiosis?
A single path of energy transfer from a producer to a consumer.
What is a food chain?
Organisms that use sunlight to make their OWN food through photosynthesis.
Things that can limit the size to which the population can grow.
What are limiting factors?
Supplies or materials that are readily available to be used for a benefit.
What are resources?
A symbiotic relationship where both organisms benefit.
What is mutualism?
A tool to show the feeding relationships between all organisms in an ecosystem.
What is a food web?
What are herbivores?
The variety of life.
What is biodiversity?
Natural resources that form much slower than the rate that they are used.
What are non-renewable resources?
A symbiotic relationship where one organism benefits and causes harm to the other organism.
What is parasitism?
These organisms make of the base of a food web.
What are producers?
These organisms use energy stored in other living organisms because they cannot make their own food.
What are heterotrophs or consumers?
An ecosystem has space for 300 birds and enough water to feed 500 birds. What factor would affect the population of birds in this ecosystem?

What is the significance of the arrows in a food chain or food web?
The arrows show the flow of energy as organisms consume each other.
These organisms can eat both plants and other animals. Can also be called secondary consumers.
What are omnivores?
How do limiting factors affect biodiversity?
Limiting Factors would decrease biodiversity.
How does air pollution affect Earth?
Causes acid rain and adds to climate change.
