the study of plants, animals and their environment, and the relationship between them
Environment
everything that surrounds an animal or plant (for example air, water, rocks and soil)
Habitat

Woodland habitat
Hedgehogs, snails, foxes and primroses
Interdependence
How organisms depend on each other for their survival
Balance
Everything is connected but it is very important that there is balance
Producer
Plants that make their own food e.g, grass p, dandelion, nettles
Consumer
Animals that get their food by eating plants or other animals
Herbivore
An animal that eats plants only e.g. rabbit, sheep, slug, snail
Carnivore
an animal that eats other animals only e.g. fox, hawk, ladybird
Omnivore
an animal that eats both plants and animals
Decomposer
Organisms that feed on dead plants and animals e.g. earthworms, bacteria, fungi.
Green plants
Food chains must start with green plants because they are the only things that can make food
Feeding level
The position of an organism in the food chain
The sun
The energy in any food chain comes from the sun
Each step
Loses more energy
Competition
Occurs when two or more organisms seek a resource that is limited
Plants compete
For light, water, minerals and space
Animals compete
Food, shelter, territory and mates
Adaptations
features that give an organism a better chance of surviving in their habitat
