FOOD CHAINS & FOOD WEBS
What does the arrow mean in a food chain
The arrow shows the transfer and movement of energy in a food chain
Explain the meaning of gravity and put it in a sentence
Gravity is a pulling force, it keeps humans on the ground on earth.
Sentence: The Sun's gravity pulls all the planets in orbit around it.
What is at the center of the solar system?
The sun
Provide a simple food chain with a producer and three consumers.
Example: Grass → Rabbit → Snake → Hawk
Explain the difference between a food chain and a food web.
Food chain shows how energy moves from one thing to another; who eats who.
Food web is many connected food chains.
Explain the word 'orbit' and put it in a sentence
orbit: To go around something
The earth orbits the sun, the moon orbits the earth.
How long does it take for the Earth to orbit the Sun once?
One year
1. What does the moon orbit around?
2. What does the earth orbit around
1. The Earth
2. The sun
Look at this food chain.
Plants ----> Grasshopper ----> mouse ----> snake ----> Eagle
Who is the producer?
Name the consumers
Who is the tertiary consumer
Producer: plants
Consumers: Grasshopper, mouse, snake
Tertiary consumer: Snake
Explain the difference between a carnivore, herbivore and omnivore.
Give an example of each
A carnivore eats only meat: lions, wolves, eagles
A herbivore eats only plants: rabbits, giraffes, cows
An omnivore eats both meat and plants: humans, bears, pigs
What keeps the planets in orbit around the Sun?
The sun's gravity
When we talk about consumers in a food chain, what words do we use instead of 1st, 2nd and 3rd?
Primary , Secondary , Tertiary
Explain why a food web is more like what happens in nature than a food chain
A food chain shows just one simple movement of energy flow in nature (like grass → deer → lion). But in real life:
More connections - Most animals eat many foods, not just one
More options - If one food disappears, animals can eat something else
A food web shows all these messy, overlapping connections - just like in real nature!
Explain what a decomposer does and give an example.
A decomposer is something that breaks down dead plants, animals, and waste into tiny nutrients. These nutrients go back into the soil, helping new plants grow.
Example: mushrooms, germs, bacteria
Write the solar system order of planets starting from the sun.
Sun - Mercury - Venus - Earth - Mars - Jupiter - Served - Uranus - Neptune
What is an apex predator?

Example: shark, lion, teacher John
