5th unit 5- L1 - food chains study guide Flashcards
(16 cards)
How do producers get their energy
Producers get energy from the sun’s energy to make food
Where do organisms get the energy they need
They get their energy from food. Some organisms can make their own food and other organisms most other living things to get energy.
How do consumers get their energy
They get their energy from the food that they eat (other living things)
Name examples of decomposers
Decomposers are fungi, bacteria, termites and many worm species
What does a food chain show
The food chain is a model that shows the path of energy and nutrients in an ecosystem
What do the arrows were present in a food chain
The arrows in a food chain represent the energy flow from one organism to another. An arrow pointing to an organism shows the living things at the organism eat an arrow pointing away from an organism shows the animal that eats that organism.
Where does the energy come from that starts the food chain
The sun
What are usually the first organisms in a food chain
Producers (such as plants and algae that use the suns energy to make food)
What are herbivores also called
Herbivores are also called primary consumers (Kawala, gorilla, elephant, manatee)
Where are all herbivores found
In every environment where plants grow
Be able to explain the difference between a tertiary consumer and a secondary consumer and give examples
Secondary consumer - carnivores that eat primary consumers (includes snakes, fish, spiders)
Tertiary consumer - carnivores that eat secondary consumers (Hawks, Hurons, lizards)
What is an omnivore
And omnivore is both predator and prey. omnivores eat both plants and meat
Be able to Trace energy flow in a food chain
Ex:
Grass. -> Cricket -> Frog
Producer -> Primary Consumer -> secondary consumer
Energy transfers from the grass to the cricket and then to the frog.
Why are predators and prey necessary an ecosystem
Predators - limit the size of prey population when they consume prey populations
prey - control the population of producers and some primary consumers by consuming them. They also support predator population because they are their food source
What would happen in an ecosystem if decomposers were not part of the food chain
Decomposers breakdown dead animals and return nutrients to the soil to start the cycle over again
Be able to do explain why producers are important to an ecosystem
Producers such as plants and algae get their energy from the sun to make their own food and they also begin the food chain. Without them primary consumers would not have a food source
