A much more realistic diagram than a food chain that shows organisms having more than one food source.
What is food web?

A vine and sunflower are both trying to get as much sunlight as possible.
What is competition?

This is the word used to describe the third consumer of the food chain?
What is tertiary?

This is what happens to the other 90% of energy.
What is lost to the environment as heat?

The arrows of a food web show this.
What is energy transfer or who is eating whom?

A tapeworm feeds off of the nutrients inside of human intestines. Doing so harms the host.
What is parasitism?
300
A cat that eats a mouse that eats a seed is in this trophic level.
What is secondary consumer?
300
If the producer in the diagram below begins with 24,000 J of energy, then this is how much the tertiary consumer would receive.
What is 24 J of energy?
300
True or False; The amount of energy the fox receives from the rabbit is equal to the amount of energy the hawk receives from the same prey.
What is true?

Algae and fungus form a symbiotic relationship. The algae uses photosynthesis to make food for itself and the fungus while the fungus provides a safe place for the algae to grow. This is known as lichen.
What is mutualism?
400
An eagle that eats a snake that eats a mouse that eats a seed is this trophic level?
What is tertiary consumer?
400
Nutrients get _____________ while energy moves in _____ _________.
What is recycled, one direction?
400
If the hawk was taken out of this food web, then this animal population would benefit immediately.
What is a snake?

A barnacle lives on a whale and travels through the ocean, which allows it to eat. The whale is not harmed and doesn't know that the barnacle is there.
What is commensalism?
500
Cat eats a mouse which eats a seed. If the mouse is taken out of the food chain from mouse traps, then this is how the cat is affected.
What is the cat population would decrease due to loss of its food source?

If the producer in the diagram below begins with 54,698 J of energy, then this is how much the quaternary consumer would receive if there were one.
What is 5.4698 J of energy?
