What are consumers?
100
Organisms such as bacteria mushrooms and other fungi that eat the remains of dead organisms.
What are decomposers?
100
Role of herbivores because they eat the producers.
What is a primary consumer?
100
At each trophic level, the amount of energy transferred to new biomass through growth and reporduction is only about 10% of what the organism eats.
What is the 10% rule?
200
The process plants use to capture energy from the Sun.
What is photosynthesis?
200
Another name for consumer that literally means "Eats others organisms. Hint: from the word "hetero" which means different

What are bacteria and fungi?
500
Next to the producer trophic level, the largest amount of biomass is in the trophic level made up of plant eaters.
What is the primary-consumer trophic level?
