How do producers create their own food? Select all that apply
Photosynthesis
Use sunlight to create sugar
Eat plants and then die, becoming food
Respiration
True or False? Higher level consumers (carnivores) rely on producers for their energy.
True-all energy comes from the sun
False-energy comes from the herbivores
During photosynthesis, energy from the ____ is transformed into chemical energy found in ______
herbivore, carnivore
sugars, the sun
sun, glucose (sugar)
atmosphere, producers
The term 'trophic level' refers to...
a role an organism plays in the ecosystem
a unit of energy
the amount of matter and organism has
The visual: Producer -->Consumer is accurate because...
It shows energy is moving from the producer to the consumer
It shows producers get energy from the consumers
It shows consumers give energy to the producers
What is this visual called?
Food chain
Food web
Trophic pyramid
Why is the trophic pyramid in the shape of a pyramid?
Because there are less carnivores in the world
Because there is less energy available at the top compared to the bottom
Because tertiary predators need to eat more
Because plants don't use as much energy
Based on the 10% rule: If the producer level (bottom) has 15,000 kilocal available, how much will the primary consumer level gain?
150,000 kcal
1,500kcal
150kcal
15kcal
Based on the 10% rule: If the producer level has 15,000 kilocalories available, how many kcal could the tertiary consumer level gain?
150,000 kcal
1,500 kcal
150 kcal
15 kcal
Fill in the blanks: Producer, _______, secondary consumer, tertiary consumer
detritivore
herbivore
primary consumer
carnivore
Choose the correct sequence for the trophic levels, bottom to top of the pyramid.
tertiary consumer, secondary consumer, primary consumer, producer
plant, herbivore, omnivore, carnivore
producer, primary consumer, secondary consumer, tertiary consumer
The direction of the arrows in this food web are important because...
They show the movement of energy from the consumed to the consumer
They show that carnivores are at the top of the food web
They show that the producers are getting energy from the consumers
Because 90% of energy is transformed (or 'lost') at each trophic level you can expect to find _______ animals at the top of the pyramid.
Less, there is less energy available
More, there are a lot of plants available
Less, carnivores don't eat plants
More, they are carnivores and easily defeat other animals
Why do living things need energy? Choose all that apply
Bodies need energy to grow, gain mass
Cells (like muscle,heart) use energy to do their jobs
Energy is the currency the body needs to do work
Organs and systems use energy to function (do work)
Why do you think decomposers exist outside of the food pyramid?
They don't need energy
They get energy from all levels
They do not count as living things
When energy is lost it goes to them
