Producers
I make my own food using sunlight. Who am I?
Plant
I eat only plants. What type of consumer am I?
Herbivore
Which way do arrows point in a food chain?
Direction of energy flow
What is a food web?
Interconnected food chains/ A group of food chains dependent on eachother
Name one decomposer.
Fungi / Bacteria / Worms
Without me, no other organisms in the chain could survive.
Producer
A fox that eats a rabbit is a ____ consumer.
Secondary consumer
What is the simplest chain: grass → rabbit → fox. Who is the primary consumer?
Rabbit
Which is more realistic: food chain or food web?
Food web
What do decomposers recycle back into the soil?
Nutrients
What process do producers use to make food?
Photosynthesis
What do you call animals that eat both plants and animals?
Omnivores
Why are food chains usually short (3–5 links)?
Energy is lost at each step
If all grasshoppers die, name one animal that will be affected.
Any insect-eater
Why can't the percentage passed on from one trophic level to the next be 100%?
Because a lot of energy is lost at each trophic level.
Grass is eaten by a rabbit. What trophic level is the grass in?
First trophic level
An eagle eats a snake that ate a mouse. What level consumer is the eagle?
Tertiary consumer
Give one example of a food chain in the ocean.
e.g., phytoplankton → fish → seal → shark
Why does removing one species affect the whole web?
Interdependence
If decomposers disappeared, what would pile up?
Dead plants and animals
What would happen to consumers if all producers disappeared?
They would all eventually die
What would happen if all primary consumers disappeared?
Secondary consumers would starve / die out
If rabbits increase a lot, what will happen to grass and foxes?
Grass decreases, foxes increase
What is the role of top predators in a food web?
Keep populations balanced
If decomposers like bacteria and fungi disappeared completely from an ecosystem, what would eventually happen to the flow of energy and nutrients?
Without decomposers, nutrients wouldn’t be recycled, plants couldn’t grow, and the food chain would collapse.
