What is an Ecosystem?

How many Ecosystems are there?

The earth has 3 Ecosystems

An Ecosystem is where living things and non-livings things interact, live and grow.

Terrestrial Ecosystem

Habitat - place organisems live and grow.

Aquatic ecosystem

Population - all individual organism of the same species.

Artifficial Ecosystem

Community - different populations can interact.

Aquatic Ecosystems

Marine Ecosystems: Seas and oceans. Includes shoreline and open oceans. Freshwater: Include standing and flowing water such as lakes and rivers. We can find freshwater in wetlands: it's covered by fresh water all year long.

Terrestial Ecosystem

Coniferous forests: Grow in cold places. Evergreen trees such as pines, wild animals suchs as deer and bears.Temeperate dediduous forests: Grow in temperate places. Decididuous leaves such as oaks. Rodents like squirrels.Mediterranean forests: Grow in warm places. Everegreen trees such us cork oaks,wild olive trees. Eagles and lynx.Tropical rain forests: Grow near the Equator,wet climates. Evergreen trees such as ferns. Monkeys and tropical birds.

Artifficial Ecosystems

Artifficial Terrestrial Ecosystems: Include Farmlands and greenhouses also Urban places. Artifficial Aquatic Ecosystems: Include Ponds and Fish farms also aquariums. Urbans Ecosystems: Include Cities that usually have natural and artifficial things.

Food webs

Food chains

All living things need energy to do evereything. Some organisms make their own food and some eat other to have energy.These relationships make food chains that have 3 levels.

Interconected food chains that produce energy, (biomass and organic material from living things). Healthy food web, the producers make more biomass than the first two consumers. Terciary consumers make the smallest amount of biomass.

Animal cell

Plant cell

Animal cell: cell membrane, nucleus, cytoplasms, vacuoles.

Plant cells: cell membrane, cell wall, nucleus, tissues, cytoplasm, vacuoles, chloroplasts.

Flowering plants

Non-flowering plants

Reproduce by spores.Don't have flowers.Mosses and ferns are part of this tipe of plants.

Reproduce by seeds. It has flowers. Angiosperms and Gymnosperms are part of this tipe of plants.

Angiosperms: have fruit with seeds in the midle. This is the most common plants.(Apples trees)

Mosses: grow in wet places with shade. They are ancient plant,they don't have roots. They normally form a soft layer on the floor.(Forests and gardens).

Gymnosperms: the seeds grow inside cones. These plants normally form big forests. They have evergreen leaves.(Firs)

Ferns: grow in wet places around water. They have roots,stem and leaves.(Hoesetails)

Humans Actions

Errors

Soluctions

We constantly make mistakes and the planet is dying

Humans can remedy many environmental problems that happen every day.

We use to much gases and pretol so the atmosphere has holes.

We can use electric cars.

Use recycled paper.

We deforest the forest too much

Use more solar panels

We smoke too much

We don't recycle rubbish

We can use recycling bins.

We can use more cloth bags.

We pollute the oceans by throwing plastics and make aquatic animals die.
