Grade 6C
Lesson objectives
Know how food chains can be used to
represent feeding relationships in a habitat.
Know that food chains begin with a plant (the
producer), which uses energy from the sun.
Know and understand the terms ‘producer’,
‘consumer’, ‘predator’ and ‘prey’
Can you remember what we mean by the word
‘habitat’?
Habitat
A habitat is a place where living things live
and find their needs.
Different
habitats on Earth:
1. Aquatic habitats: ocean, lake, pond, river..
2. Terrestrial habitats: prairie, forest, desert,
mountain….
Food chain
A food chain is a series of events in which
one organism eats another and obtains
energy.
A food chain shows one possible path
along which energy can move through an
ecosystem.
What is in a food chain?
Producers
Consumers
decomposers
producers
Make their own food by photosynthesis.
Green plants use energy from the sun to
make their own food.
Producers are on the bottom of the food
chain.
Photosynthesis.
Consumers
Consumers hunt, gather, and store food
because they cannot make their own.
consume= to eat or to feed
Three types of consumers:
1. Herbivores
2. Carnivores
3. Omnivores
Herbivores: animals that eat only plants
Carnivores: animals that eat only meat
Omnivores: animals that eat both meat and
plants
Consumers are also classified as:
•Primary
consumers: are consumers that feed off
producers.
•Secondary
consumers: are consumers that feed on
primary consumers and sometimes consume producers.
•Tertiary
consumers: are consumers that can feed off
secondary and primary consumers and sometimes
consume producers.
•Quaternary
consumers
Decomposers:
Organism that break down dead animals
and plants and return the nutrients to the
soil.
Predator and prey
Predator: an animal that captures and eats
other animals.
Prey: the animal that is captured and
eaten.
Run for your life!
Let’s look at a food chain
it is a simplified way to look at the energy that passes from
producers to consumers.
What is a food web?
A more realistic way of looking at the
relationship of plants and animals in an
environment.
We use arrows to show feeding relationship.
Several food chains linked together.
A predator from food chain maybe linked to
the prey of another food chain.
Example of food web
