Key Words
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?
This is the form of energy transfer that happens when 2 objects at different temperatures come in contact.
What is conduction?
This group of organisms make up the largest percentage of Earth's total biomass.
What are plants?
The process in which plants convert sunlight into energy.
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?
This form of energy transfer involves the movement of liquids. (ie. air or water)
What is convection?
Most of the biomass in a forest ecosystem is stored in this component.
What are trees?
This desert ecosystem is the largest hot desert in the world.
What is the Sahara Desert?
These organisms eat producers and are in the second level of the energy pyramid.
What are primary consumers?
These organisms break down dead materials and recycle nutrients.
What are decomposers?
This is the term for energy an object has because of its motion.
What is kinetic energy?
Despite their size, these animals only represent a small percentage of total animal biomass.
What are humans.
This type of wetland ecosystem is dominated by grasses, being very common in the Everglades.
What is a marsh?
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?
This type of energy is stored in chemical bonds and released during a reaction.
What is chemical energy?
This group outweighs all wild mammals by a great margin, mostly due to domestication.
What are livestock?
This ecosystem is often called the "rainforest of the sea".
What are coral reefs?
Biomass is usually measured in these units.
What are grams per square meter?
Organisms at the top of the energy pyramid, having no natural predator.
What are apex predators?
What is radiation?
This biome stores the highest biomass per unit area, mostly being trees.
What is a tropical rainforest?
These large animals are considered the keystone species in African savannas.
What are elephants?
