Explanation:

1. The first blank refers to the ecological pyramid showing organism sizes, so it is an energy pyramid.
2. In a size/energy pyramid, producers (like plants) are the largest group at the base.
3. The smallest group at the top of the pyramid are tertiary consumers.
4. As you move up trophic levels, there is an energy loss (90% of energy is lost, only 10% transferred).
5. The percentage of energy lost between levels is 90%.
6. Producers such as plants and phytoplankton perform complete photosynthesis to make their own glucose.
7. Autotrophs is the term for producers that make their own food.
8. Heterotrophs are organisms that must consume other organisms for energy.
9. Heterotrophs must consume other producers or consumers to obtain energy.

Answer:

1. Observing the sizes in an energy pyramid, the producers are the largest group, primary consumers 2nd largest, secondary consumers 3rd largest, and tertiary consumers are the smallest. This is an important concept regarding how food chains and food webs are represented by scientific models to show energy pathways among living organisms. There is a loss of 90% energy as you move up each successive level of the pyramid. Autotrophs are producers like plants and phytoplankton that complete photosynthesis to make their own glucose, or food. Heterotrophs are living organisms that must consume either producers or other consumers to obtain energy.
