Biotic Factors: Living
Abiotic Factors: Non-living
Big Mac
All the energy within our food originates from the sun – transferred through food chains...
It comes from the sun
Food Chains
A food chain shows what eats what in a particular habitat.
The arrow points in the direction of the energy flow.
e.g.
Food Chains
Producer:•Makes their own food from carbon dioxide and water using the energy from sun.Primary Consumer:•Eats (Consumes) producers Secondary Consumer:•Eats primary consumers
Producer Primary Consumer Secondary Consumer
Food Webs
Just like food chains except in most habitats, more than one organism normally eats/is eaten by other organisms.
• Therefore, food webs are food chains which interlinks with each other.
• Identify 3 food chains in this food web.
Food Webs
Herbivore:Animal that eats only plants.
Carnivore:Animal that eats other animals.
Omnivore:Animal that eats plants and other animals.

What is another name for a primary consumer?
Fox & Sun
Producers (e.g. grass) grow via photosynthesis, getting their energy from the Sun
This energy is used to allow the producer to grow (increase in biomass), eventually being passed on to consumers (e.g. a rabbit) when they eat it
When a fox eats the consumer energy is again passed on, so completing the energy chain from Sun to producer to consumer to secondary consumer (fox)
Sun → Grass → Rabbit → Fox
