Where all energy in an ecosystem begins.
What is the Sun?
A model that shows one pathway of energy transfer.
What is a food chain?
This trophic level has the most energy available.
What are producers?
A drought reduces plant growth. This trophic level is affected first.
What are producers?
This has hands and a face, but no arms or legs.
What is a clock?
An organism that makes its own food.
What is a producer?
In the chain Grass -> Mouse -> Snake, this organism is the primary consumer.
What is the mouse?
The percent of energy that is transferred to the next level.
What is 10%?
If a wildfire destroys the grass in an ecosystem, this happens to the population of primary consumers.
What is the population decreases?
This is always in front of you, but can never be seen.
What is the future?
These organisms break down dead animals and return nutrients to the soil.
What are decomposers?
A network of many connected food chains.
What is a food web?
Secondary consumers eat these organisms.
What are primary consumers?
The following food chain takes place in a local lake: Algae -> Mayfly -> Bluegill -> Largemouth Bass. This will happen if the Bluegill population decreased.
What is the Mayfly population will increase, while the Largemouth Bass population will decrease.
This is something you can catch, but cannot throw.
What is a cold?
Arrows in a food chain/food web represent this.
What is energy transfer?
In Grass -> Grasshopper -> Frog -> Hawk, this organism receives the least energy.
What is the hawk?
If producers have 5,000 energy units, primary consumers receive this amount.
What is 500 units?
A hiker notices a fallen log that is covered in mushrooms and fungi, breaking it down into soil nutrient. This is the role of the mushrooms.
What is a decomposer?
These month(s) have 28 days.
What is all of them?
The form of energy that is lost at each trophic level.
What is heat (thermal energy)?
If primary consumers are removed, this will likely happen to producers and secondary consumers.
What is producers will increase and secondary consumers will decrease?
Beginning at 10,000 energy units at producers, this amount reaches tertiary consumers.
What is 100 energy units?
In an ecosystem, a caterpillar is seen eating a tomato plant and then a bird eats the caterpillar. The bird is this type of consumer.
What is a secondary consumer?
This is as light as a feather, yet the strongest person can’t hold me for 5 minutes.
What is a breath?
