5th unit 5- L1 - food chains study guide

Question 0

How do producers get their energy

Answer 0

Producers get energy from the sun’s energy to make food

Question 1

Where do organisms get the energy they need

Answer 1

They get their energy from food. Some organisms can make their own food and other organisms most other living things to get energy.

Question 2

How do consumers get their energy

Answer 2

They get their energy from the food that they eat (other living things)

Question 3

Name examples of decomposers

Answer 3

Decomposers are fungi, bacteria, termites and many worm species

Question 4

What does a food chain show

Answer 4

The food chain is a model that shows the path of energy and nutrients in an ecosystem

Question 5

What do the arrows were present in a food chain

Answer 5

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.

Question 6

Where does the energy come from that starts the food chain

Answer 6

The sun

Question 7

What are usually the first organisms in a food chain

Answer 7

Producers (such as plants and algae that use the suns energy to make food)

Question 8

What are herbivores also called

Answer 8

Herbivores are also called primary consumers (Kawala, gorilla, elephant, manatee)

Question 9

Where are all herbivores found

Answer 9

In every environment where plants grow

Question 10

Be able to explain the difference between a tertiary consumer and a secondary consumer and give examples

Answer 10

Secondary consumer - carnivores that eat primary consumers (includes snakes, fish, spiders)

Tertiary consumer - carnivores that eat secondary consumers (Hawks, Hurons, lizards)

Question 11

What is an omnivore

Answer 11

And omnivore is both predator and prey. omnivores eat both plants and meat

Question 12

Be able to Trace energy flow in a food chain

Answer 12

Ex:
Grass. -> Cricket -> Frog
Producer -> Primary Consumer -> secondary consumer

Energy transfers from the grass to the cricket and then to the frog.

Question 13

Why are predators and prey necessary an ecosystem

Answer 13

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

Question 14

What would happen in an ecosystem if decomposers were not part of the food chain

Answer 14

Decomposers breakdown dead animals and return nutrients to the soil to start the cycle over again

Question 15

Be able to do explain why producers are important to an ecosystem

Answer 15

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
