Vocabulary
100
Do plants depend on people?
No, they can function on their own. People depend on plants as much as plants depend on people.
100
What is a producer?
An organism that receives its energy from the sun
100
What is the difference between an herbivore and a carnivore?
An herbivore only eats plants and fruits, while carnivores eat other animals
100
How much energy is passed between each trophic level?
10%
100
What is ecology?
Ecology is the branch of biology that deals with the relationships of organisms to one another and their physical surroundings
200
Can organisms change trophic levels?
Yes, humans feed on different levels (eat producers, primary consumers, and secondary consumers)
200
What is a consumer?
A living thing that cannot make its own food
200
What type of animals are considered secondary consumers?
Secondary consumers can be both carnivores and omnivores, as they eat the primary consumers.
200
Which consumer will receive the most energy? A primary consumer or a secondary consumer?
Primary Consumer
200
What is an energy pyramid?
An energy pyramid is a model of energy flow in a community. Each level represents different groups of organisms that might compose a food chain.
300
Herbivores are docile and carnivores are vicious.
No, both can have either personality type. Their diet is not the only ruling factor.
300
A mouse eats a plant, what trohpic level is the mouse?
Primary consumer
300
What is the difference between a food chain and a food web?
Food webs show how plants and animals are connected in order to survive, while a food chain shows a single path of who eats who.
300
A mouse eats an insect that had 1,000 J of energy. How much of that energy is passed on to the mouse?
100 J
300
What is a food chain?
A food chain is a series of organisms each dependent on the next as a source of food
400
The top of the food chain has the most energy.
False, it receives the least amount of energy, as it only gets 10 percent of the energy of the organism they consume.
400
A raven eats a butterfly, which ate nectar from a flower. What trophic level is the raven?
Secondary Consumer
400
What is the primary source of matter and energy that is received from the sun?
Producers, plants receive their energy from the sun and pass on their energy to their consumers
400
The sun shines down 10,000 J of energy to the producer, how much of that energy is received by the producer?
1,000 J
400
What is a food web?
A food web shows how energy is passed on from one living thing to the next, using all the animals that live together in an ecosystem.
500
Food webs are interpreted as simple food chains.
No, it shows complex relationships between organisms.
500
What level are the following organisms: Raven, tree, mountain lion, insect?
Tree- producer Insect- Primary Consumer Raven- Secondary Consumer Mountain Lion- Tertiary Consumer
500
What is the measurement representing the amount of heat energy lost in the system?
Entropy
500
If a producer received 10,000 J of energy from the sun, how much of that energy would a tertiary consumer receive?
10 J
500
What is the rule of 10?
The amount of energy that is passed between trophic levels decreases as it moves through. As little as 10% is transferred to the next level.
