a food chain shows how energy passes through one organism to another

the arrows of a food chain show how energy flows through each organism

the first organism in the food chain is called a producer and the animals that eat the plants and other animals are called consumers

only 10 percent of the energy is passed on whilst the other 90 percent is used for making simple sugars (when it comes to plants) and MRS GREN

MRSGREN stands for movement,reproduction,sensitivity,growth,respiration,excretion and nutrition

a food web is a network of interlinked food chains which show all sources of food for an organism

scavengers, decomposes, and parasites are not included in a food chain because they can get their energy from any leve of the food chain

parasites live on alive organisms blood without killing it

plants make their own food (photosynthesis)

animals have to find their own food

an eco-system is an area where organisms interact with one another
