How do ecosystems compare?
- 2. Do you remember what’s an ecosystem? Ecosystem is a place where living & non-living things interact. Example s: Forest Ocean Dessert
- 3. Do you know that every ecosystem has its own climate? Wait please, I can’t understand what’s the meaning of climate. Well, let’s see what is the climate?
- 4. Take a look at this picture What is this? Desert Can you tell the weather during daytime in the desert? It’s so hot Is it hot all over the year or just in a certain time of the year?No, it’s hot all over the year
- 5. 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
- 6. Climate in an ecosystem can be: Wet Dry Hot Cold Ocean Desert Arctic
- 7. Can you tell the climate in these regions? Cold climate
- 8. Hot & dry climate Wet climate
- 9. Now let’s get to know the types of ecosystems: (1) Desert
- 10. - The desert has a dry climate. - During daytime: (Hot) - During night: (Cold) - Example: “Sonoran desert” in North America. Climate in the desert:
- 11. 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 = Change to survive
- 12. 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. Hump Camel
- 13. -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.
- 14. In the daytime: In the Night time: -Turtles hide from the sun in their shell. -They come out from their shell.
- 15. 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.
- 16. Cactus plant Cactus plants store water in their stems. They also have very short roots to absorb “take” the water quickly from the soil Stem Root s
- 17. (2) Forests
- 19. -The climate in the tropical rainforest is hot & wet “as it rains all the time of the yea -Climate in the tropical rainforest:
- 20. - 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)
- 21. - 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 it’s easy for the animals to find their food & water”
- 22. Temperate forest
- 23. - Climate in the temperate forest: -The temperate forest differ from the tropical rainforest. -It’s climate changes in seasons. “It’s warm in summer , but it’s cold in winter” -It rains in the temperate forests , but they have
- 24. How does temperate forest looks like in different seasons? Spring Summer Fall Winter
- 25. Forests Tropical rainforest - Hot and wet “rainy” all year. - Has more living things than any other environment. Temperate forest - Warm summers and cold winters. - Gets less rain than tropical rainforests.
- 26. (3) Wetland
- 27. Properties of the wetland: -It’s covered with water “wet” most of the year. -It’s found at the edges “sides” of the rivers, lakes & oceans.
- 28. - It may have: “fresh water - salt water “
- 29. - Wetland also prevent flooding. “when water level is so high that can cover the houses” because they are like sponges that absorb water.
- 30. - Plants of the wetland help to clean dirty water, because it takes “absorb” the wastes from the water. Oh yes, I get it. It’s like the “Hoover that cleans the carpets”
- 31. (4) Oceans
- 32. - It’s the largest ecosystem on the earth. - The ocean: is a large body of salt water.
- 33. - 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)
