What are the levels of organization from smallest to largest?
cells-tissues-organs-organ system- organism
What is the process that plants undergo to make their own food?
Photosynthesis
What do the arrows show you in a food web/food chain?
The direction of the energy flow in the ecosystem
This is the name of the energy we get from sunlight
What is radiant energy?
Where in a food chain would a producer be located?
It is the first organism in the chain.
What trophic level is at the bottom of an energy pyramid?
Producers
What are the reactants in photosynthesis?
Carbon dioxide, water, sunlight
This is how much energy is passed on to the next organism in a food chain.
10%
This is the type of energy that is stored in bonds between molecules. It is found in food (including glucose!).
What is chemical energy?
_____ energy is transformed into _____ energy during photosynthesis.
radiant to chemical
The solar energy of sunlight is transformed into ____ energy when glucose is created.
Chemical
What are the products of photosynthesis?
Oxygen and glucose
In a food chain of grass-> gasshopper-> mouse-> snake-> hawk. What is the tertiary consumer?
Snake
What is the energy transformation that happens during photosynthesis?
radiant energy to chemical energy
If a rabbit eats a carrot to get energy to stay warm on a chilly day, what energy transformation is this?
chemical to thermal
This is a diagram that shows the total amount of energy contained in each trophic level.
Energy pyramid
What level of a trophic pyramid has most available energy?
Producers
This is a series of overlapping food chains.
Food web
This is the energy present in the sun when the nucleus of the atoms combine.
Nuclear energy
In a food chain of grass-> gasshopper-> mouse-> snake-> hawk. What would happen if a pesticide decreased the grasshopper population?
Mouse population would decrease.
When looking at a food web, how would you know if two organisms would compete for the same food?
There would be arrows from the food source going to both consumers.
Which structures are found in all producers?
Chloroplasts
What receives energy directly from the producers?
Primary consumers
What is the energy transformation when someone eats a protein bar and then runs in a marathon?
chemical to mechanical
