Ecosystem Interaction between living things and non living

things in a place. Ex: Aquatic, terrestrial.

HabitatI’ts the place where an organism finds the

FOOD, WATER and SHELTER it needs, to live and survive. Ex: ants colony.

BiomeIt is a large area in witch we find the same type of living organisms: animals, plantsand microorganisms. Ex: Desert

Food ChainThere are three groups: each group eats the

group below .Living things: animals, plants, microorganisms.Producers: they produce their own food. Ex: Grass, trees and plants. Cosumers: They eat grass, plants and trees

(primary C.),other animals (secondary C.)omnivores ( eat plants and animals) Decomposers : They eat dead animals. To obtain energy.

AQUATIC ECOSYSTEMSAquatic ecosystemS are found in water. Rivers, lakes,

seas and oceans are aquatic ecosystems.There are two

types: fresh water or salt water ecosystem.Rivers: These are cold rivers and warm rivers. In cold

rivers we can find, fish like trout of salmon. In warm rivers you can find fish like pirarucu.

Lakes : a lot of plants and animals live in lakes for example amphibians, duck s and gees.

Seas and oceans: cover most of the Earth surface. Seawater is salty, there is big diversity of animals and plants in oceans and seas.

TERRESTRIAL ECOSYSTEMSForests:

* They have a lot of trees because of RAIN and TEMPERATURE.* In forests we can find: - Decidious trees ( fulla caduca) - Evergreen trees (fulla perenne)

* They are divided in : - Temperate forests: there are four seasons. - Tropical forests: it is hot all year.

Grassland:* The plants are grasses.* They have long periods of rain and periods of drought (sequera)* There aren´t enough water to be a forest.* They are divided in: - Prairies: They have four seasons. - Savannah: It rains a lot. There animals like giraffes, zebras…

Deserts:Deserts are hot an dry.Desert cover 20% of surface.Temperature in deserts experience great variations.Plants and animals that live in deserts adapt to

survive in this extreme conditions.

Tundra:They are cold areas covered with ice. The soil that is permanently frozen, it is called

permafrost. Trees cannot live in frozen soil , so there are no

trees. Plants grow during the summer, when the light of the

sun partially melts the surface of the ground.
