19 Types of Ecosystems Deserts are very dry ecosystems. Desert plants and animals can survive with very little water.
20 Desert PlantsDesert plants, such as cactus, have thick stems that store water.The roots of a cactus lie just below the soil and spread far from the plant.
21 Grassland EcosystemsGrasslands are dry, often flat areas of land that are hot in the summer and cold in the winter.They get more rain and snow than deserts but less that most other ecosystems.
22 Plants The main plant in a grassland ecosystem is grass. There are not many bushes in the grassland.Trees are found only by rivers and streams.
23 Saltwater Ecosystems Saltwater ecosystems are oceans. Oceans cover about three –fourths of Earth’s surface, so there are more saltwater ecosystems than any other.
24 Sharks, sea turtles, corals and octopus are all ocean animals. So are whales and seals.
25 Freshwater Ecosystems Rivers, ponds, lakes and streams have fresh water.Lakes and rivers are closely tied. Some lakes are the source for some rivers. Important rivers, most often, originate from lakes. Some rivers end in lakes.Since both rivers and lakes are freshwater and flow in and out of each other, they share similar characteristics and many species reside in both habitats.
26 Forest EcosystemsForest are ecosystems in which many trees grow.
27 Tropical Rain ForestA tropical rain forest grows where it is hot and wet all year long.Animals such as jaguars and monkeys live there.
28 Deciduous Forest What's A Temperate Deciduous Forest Like? One of the most interesting features of the temperate deciduous forest is its changing seasons.The word "deciduous" means exactly what the leaves on these trees do: change color in autumn, fall off in the winter, and grow back again in the spring. This adaptation helps trees in the forest survive winter.
29 Drawing Conclusions Suppose all the plants in one ecosystem died. What do you think would happen to that ecosystem?Why?
