A HABITAT is the place where a plant or animal lives

Different plants and animals are suited to particular habitats

Each animal has a body and a life-style which help it live where it does Each is adapted to its habitat

There are many different habitats in the seas and oceans

STEP Plants and animals can live in the water, attached to the sea bed, or burrowing inside the sea bed

The oceans are HUGE!!! The average depth is 3700 metres The deepest part is more than metres deep Only 5% is shallower than 200 metres The total volume is about 1000 million cubic kilometres

Out in the deep ocean, different depths form different habitats The deep makes up 80% of the habitat space on earth

As you go deeper into the ocean, it gets darker It also gets colder: Below 1000 metres depth, the temperature of the ocean is about the same as your fridge

The water pressure also increases : At a depth of metres, the water pressure is 1 tonne on each square centimetre

Most life is in the SUNLIT ZONE - the top 200 metres Beneath this is the TWILIGHT ZONE, where sunlight is too dim for plants to grow The deepest parts of the ocean are in the DARK ZONE Different animals live at different depths in the ocean They have different ways of finding food, and not being eaten!

In the shallow parts of the oceans, there is enough light for plants to grow on the sea bed

Plants growing attached to the seabed, like this kelp, can only grow where the ocean is shallow enough to let through enough light for growth

Coral reefs form a very important habitat in shallow tropical seas

Dave Peake

The coral is built by small animals There are several different types of coral Many different animals live on coral reefs

A habitat is where a plant or animal lives Different habitats have different plants and animals You have seen that -

There are different habitats in the sea Animals live in different depth zones in the ocean You have seen that -

Plants can only grow in shallow water Coral reefs are an important habitat in tropical seas You have seen that -

NOTES for USERS The material in this slide show is designed to support the teaching of science at Key Stage 1 A full description of the slide show, and linked activities for students, can be found on the National Marine Aquarium (NMA) web-site: Teachers are free to amend the slide show in whatever way they feel fit, or to use slides in other contexts. However, please note that neither the NMA nor the designers will accept responsibility for modifications, and original material remains copyright of the NMA Individual images used in the slides are copyright of NMA or STEP, except where acknowledged separately The slides have been set up to display as A4 landscape format. If they are incorporated into other slide sequences with different display settings, change in aspect ratio and text location will occur The slide sequence contains the minimum of effects and transitions. However, there are some automated animations, and teachers will wish to make sure that they are familiar with the sequence before use in class Use the PowerPoint notes viewer to obtain additional information for some slides
