5 STEPS OF GERMINATION
1. as soon a seed receives water and warmth the embryo starts to grow.
2. The root pushes its way out of the seed coat and begins to anchor to the soil so the seed can suck up water and minerals.
3. the stem begins to develop and grows upward searching for light
4. stems continue to grow and leaves form
5. germination is complete and the plant makes its own food through the leaves and can do photosynthesis
3 MAIN WAYS SEEDS ARE DISPERSED
1. WIND-the seeds fly in the air such as seeds from a dandelion or maple seeds that look like helicopters fall off maples trees
2. WATER-the seeds float from one ocean to another or by rain. The coconut seed floats and travels.
3. ANIMALS-they are carried in insect and birds mouths and chipmunks carry seeds and bury them. They can also be carried on the fur of animals.

2. The robin preys on a caterpillar.
3. The hawk preys on the robin.
4. The earthworm feeds on the dead hawk and the nutrients passon to the soil later on.
2 examples of PRODUCERS, CONSUMERS, and DECOMPOSERS
1. PRODUCERS-grass and trees
2. CONSUMERS-human or cow
3. DECOMPOSERS-fungus or bacteria
What are the 2 main fuctions of a seed?
1. It contains stored food that helps young plants grow.
