Food Webs
Arrows on a food webs always point in this direction
What is towards the consumer
These organisms get the least amount of energy in an energy pyramid
What are the Tertiary Consumers (Top of the pyramid)
These factors are the living things in an ecosytem
All the living and nonliving things in an area.
What is an ecosystem?
In the following food chain, this will happen if the frog is taken out.
grass --> frog --> snake --> hawk
What is the grass will increase and the snake and hawk will decrease?
This is where all the energy in a food web comes from
What is the sun?
This is the amount of energy passed from each energy level to the next
What is 10%?
This is biodiversity
What is the different amount and variety of species in an area?
Consumers that only eat other consumers
What are carnivores?
In the following food chain, these two organisms have a producer-consumer relationship.
Trees --> Elephants --> Cheetahs
What are the trees and elephants?
If a primary consumer becomes extinct, this population show grow (increase).
What is the producers?
Energy in an energy pyramid is transferred in this direction.
What is from the bottom to the top?
Sustainability is important for this reason
What is if an organism is removed the food web can still survive.
Autotrophs
What are producers/plants?
In the following food chain, this is a primary consumer.
Berries --> Fruit Fly --> Frog --> Snake
What is the fruit fly?
These organisms are the key to recycling nutrients back to the soil, continuing the energy cycle.
What are decomposers?
What is the first consumer level?
Soccer field are most often made of one single type of grass which makes the biodiversity this.
What is low or poor?
Organisms that break down other organisms to return the energy back to the environment.
In the following food chain, this would occur if the snake were removed.
berries --> fruit fly --> frog --> snake --> hawk
What is the frog population would increase and the hawk population would decrease?
Omnivores eat these.
What are auto- and heterotrophs?
This level of the energy pyramid consumes the herbivores.
What is the secondary consumer level?
Greater Biodiversity = Greater ______
Organisms that eat both producers and consumers.
What are omnivores?
In the following food web, this is the tertiary consumer.
berries --> fruit fly --> frog --> snake --> hawk
What is the hawk?
