Ecosystems

The study of living things and their environment

Can be large or small and is made up of two parts, living and non living

Water, light, oxygen and temperature and examples and have a huge effect on plants and animals

Plants, animals and microbes are all part of the community and depend on eachother to survive

(Plants) Make the food for consumers

(Animals) Eat the food from producers and also supply food for other consumers

All living things produce waste and in all ecosystems there are organisms who get rid of them. They recycle any chemicals and keep the soil healthy for growth

Made up of producers and consumers that make a 'chain of feeding' and are the basic relationship with ecosystems

• Different food chains interconect to create food webs
• Plants are usually placed at the bottom, then herbivores and so on upwards

Plants/Animals have special features to help it 'fit in' and survive in its environment, these are called adaptions

• Ash helps fertilize poor soils
• Plants can resprout and grow
• Some environments depend on fires

• Deposit silt on fields and replenish topsoil
• Help guarantee fertility
• Refill wetlands and flushes out costal estuaries

• Plants produce drought resistance seeds surviving decades
• Animals have adapted to conserve water

A resource that has been created through the acts of humans, it doesnt exist in nature

Not created through humans and exist naturally

A natural source that cant be reused, grown or remade because it cant be replenished in a short peroid of time e.g. Petrolium and natural gases

Natural resources that can be replenished in a short period of time e.g. solar and wind energy
