Why is Photosynthesis important for a producer
It gives the producer energy
How does Photosynthesis work
The producer takes in Sun energy, CO2, and H2O. It then produces C6H12O6 (Glucose) and O2
What is the difference between a food chain and food web
A food chain has only one predator/prey path while a food web has multiple predator prey paths.
What is the difference between a food chain/web and a energy pyramid
Food chain/web tells us what gets eaten while a Energy pyramid tells us how much energy something gets from eating another thing.
Advantages of using a food chain
1.) One to one 2.)Single path for predator 3.) Clear
Advantages of using a food web
1.) Shows a variety in animals diet 2.) More complete than a food chain
Advantages of using a energy pyramid
Shows how much energy is transferred between each animal
Pros and Cons of food chain
Pros: One to one, Clear Cons: Does not show a varied diet, Only one predator
Pros and Cons of food web
Pros: Multiple predator paths, Shows varied diet Cons: Unclear/harder to understand
What are the levels of food chain/web
1.) Producer (first) 2.) Primary 3.) Secondary 4.) Tertiary (last)
What does each level for a energy pyramid represent
A 10% energy reduction for each level
What is the difference between a Primary and secondary Succession
Primary succession is when life starts in a new area and secondary succession is when life starts in that area after a major catastrophic event
