Identify the energy roles of the following organisms in a pond ecosystem: tadpole, algae, heron.
What is algae: producer Tadpole: herbivore/first level consumer Heron: consumer/ carnivore/ second level consumer
400

Why are there fewer tertiary consumers than primary consumers in a food chain or energy pyramid?

Since only 10% of the energy is transferred in a feeding relationship, tertiary consumers receive less energy than primary consumers.  Therefore they have to eat more to survive and there isn't enough food available to support a large number of them.

If there are 3000 Kcals of energy available to the producers, how much energy is available for the primary, secondary, and tertiary consumers?

primary consumer: 300 Kcals,  secondary consumer: 30 Kcals,  tertiary consumer 3 Kcals

500

In a food chain that goes from producer to tertiary consumer, what would happen at each level if the secondary consumer was removed?

What is the population of tertiary consumers would decrease, primary consumers would increase and producers would decrease?
