Every living thing needs energy in order to live. Every time animals
do something (run, jump) they use energy to do so.
Animals get energy from the food they eat, and all living things get
energy from food.
Plants use sunlight, water and nutrients to get energy (in a process
called photosynthesis).
Energy is necessary for living beings to grow.
A food chain shows how each living thing gets food, and how
nutrients and energy are passed from creature to creature.
Food chains begin with plant-life, and end with animal-life.
Some animals eat plants, some animals eat other animals.
A simple food chain could start with grass, which is eaten by rabbits.
Then the rabbits are eaten by foxes.
A food chain is the sequence of who eats whom in a biological
community (an ecosystem) to obtain nutrition.
A food chain starts with the primary energy
source, usually the sun or boiling-hot deep sea
vents.
The next link in the chain is an organism that
makes its own food from the primary energy
source.
