How do ecosystems compare?

Do you remember whats an ecosystem?Ecosystem is a place where living & non-living things interact.

Examples:

ForestOceanDessert

Do you know that every ecosystem has its own climate?

Wait please, I cant understand whats the meaning of climate.

Well, lets see what is the climate?

Take a look at this picture

What is this?DesertCan you tell the weather during daytime in the desert?Its so hotIs it hot all over the year or just in a certain time of the year?

No, its hot all over the year

So, we can say that the climate in the desert is: hot

Climate: It is a pattern of weather in a place over a long time

Climate in an ecosystem can be:WetDryHotCold

Ocean

Desert

Arctic

Can you tell the climate in these regions?

Cold climate

Hot & dry climate

Wet climate

Now lets get to know the types of ecosystems:(1) Desert

9

- The desert has a dry climate. - During daytime: (Hot)

- During night: (Cold)

- Example: Sonoran desert in North America.

Climate in the desert:

How can animals & plants survive in the desert?

The desert is a very hot & dry place to live in, so in order for the animals & plants to survive there, they have to adapt to the desert.Adapt = have a body part or act to survive

Examples

Camels can survive in the desert for a long time,It stores the food & water in its hump back, & when the camel feels hungry, it eats the stored food & water from its hump.

HumpCamel

Snakes, lizards & rats hide from the sun under big rocks .In the daytime:

In the Night time:

- Snakes, lizards & rats come out from under the rocks when the sun is gone.

In the daytime:

In the Night time:

Turtles hide from the sun in their shell.They come out from their shell.

In the daytime:

-Desert foxes hide from the sun in caves .In the Night time:

They get out of the caves to search for food & water.

Cactus plantCactus plants store water in their stems.They have roots just below the surface to absorb take the water quickly from the soilStemRoots

(2) Forests

Tropical Rainforest

The climate in the tropical rainforest is hot & wet as it rains all the time of the year.

-Climate in the tropical rainforest:

- Plants in the tropical rainforest:

As the climate is rainy wet all the year in the tropical rainforest, it has very tall plants & trees.(As there is plenty of water for the plants to grow)

- Animals in the tropical rainforest:

-As the tropical rainforest has plenty of water & plants in it,So we can find many animals living there more than any other place.

As its easy for the animals to find their food & water

Temperate forest

- Climate in the temperate forest:The temperate forest differ from the tropical rainforest.Its climate changes in seasons.Its warm in summer , but its cold in winter

It rains in the temperate forests , but they have less rain than the tropical rainforest which rains all the year.

How does temperate forest looks like in different seasons?SpringSummerFallWinter

Forests

Tropical rainforest- Hot and wet rainy all year.- Has more living things than any other plants.

Temperate forest- Warm summers and cold winters.- Gets less rain than tropical rainforests.

(4) Oceans

Its the largest ecosystem on the earth.

The ocean: is a large body of salt water.

The earth has 5 five oceans.

If we take a closer look at the ocean, we will find almost all the living things in it living in the upper shallow part of the ocean.

- (Because Sunlight warms the water and gives the producers (ex. Water plants) the energy to make their food so Animals will find the food they need)
