This level of an energy pyramid has the most energy and biomass avaliable.
What are primary producers?
This trophic level includes organisms like grass, shrubs, and algae that produce their own food using photosynthesis.
What are primary producers?

At each level of a trophic pyramid, some energy is released as...
This happens to the energy and biomass as you move up the energy pyramid.
What is it decreases?
These animals take up the third trophic level, eating primary consumers.
What are secondary consumers?
Which macromolecule is used to help build and repair muscle tissues?

an autotroph is also known as what?
These organisms eat producers and are in the second level of the energy pyramid.
What are primary consumers?
These large animals are considered the keystone species in African savannas.
What are elephants?
What is the monomer of a protein?
amino acid
which trophic level has the most biomass?
producers!
This percentage of energy is transferred from one trophic level to the next.
What is 10%?
The second level of an energy pyramid, directly feeding on producers.
What are primary consumers?
What gives a molecule the potential for more energy when broken down?
More carbon/carbon bonds
Scientists initially studying the decline of certain penguin populations in Antarctic regions found that the penguins’ food source, a small animal known as krill, had dropped by 80%. These scientists are now studying the reduction in the number of tiny photosynthetic organisms that are the food source of the krill. The decline of the penguin population was a direct effect of the disruption of a

Carbohydrates
Organisms at the top of the energy pyramid, having no natural predator.
What are apex predators?
Which molecule contains the most carbon/carbon bonds?
Lipids/fats
We generate energy (ATP) by breaking down what type of molecules?
Macromolecules or ORGANIC (contains carbon) molecules
