3  The place where an animal or plant lives and grows: a home.  Everything around a plant or animal is its habitat.

4  They are animal homes that are in the water such as the ocean, streams, rivers, swamps, ponds.  Water related environments( aquatic) include those with fresh water or salt water.  Example include ponds, marshes, swamps, streams, rivers, and oceans.

5  It is water that has very little salt in it.  Lakes, rivers, ponds, and some marshes are freshwater ecosystems.  We drink fresh water.

6  It is water that has a lot of salt in it.  Oceans and seas contain salt water.  The oceans are Earth’s largest ecosystem in size.  There are many kinds of animals and plants living in salt water.

7  animal homes that are on the land such as tundra, grassland, desert, tropical rain forest, and forests ( coniferous, and deciduous).  They are dry- land environments( terrestrial).

8  They are areas that get very little rainfall.  Deserts are land communities which can be hot or cold with very little water.  In hot deserts the most often seen plant is the cactus.  A desert plant has:  - a thick skin  - a thick stem  - very shallow roots  - and spine like needles  Jack rabbits, tortoises, rattlesnakes, lizards, roadrunners, and coyotes are the common types of animals.

9  The tundra area has the smallest population of plants and animals on earth because of the short growing season and cold conditions.  Very small plants grow there and little or no trees.  Animals such as the reindeer and polar bears live here.

10  The grassland area is a flat area with few trees and lots of tall grass.  Animals that live in herds and are herbivores such as cows, buffaloes, deer, zebras, antelopes and giraffes live in this area.  Predators like the lion live also here.

11  An area in which the main plants are trees.  There are many animals living there, too.  Forests need rain and sunshine, and very high temperatures.

12  This forest is hot, humid, and rainy with many trees and green plants.  It has the largest population of animals and plants. All types of animals live there including many insects and amphibians.  It has three main layers, where animals and plants make their own homes. They are:  - the canopy- or top part,  - the understory- below the canopy  - the forest floor- the lowest layer.  Trees are very tall, and they have pole like trunks.

13  They grow where there is a lot of rain.  It does not get too warm or too cold in there.  It has a lot of very tall thick trees.  It has the same layers as in the tropical rain forest.

14  Forests that have trees whose leaves  - change color and fall off in the fall,  - die in the winter,  - bloom in the spring,  - and stay in the trees in the summer.  A forest of trees that lose and re-grow their leaves each year.  We live in a deciduous forest.  Some of the animals living here are: insects, snakes, birds, deer, and bears.  There are ferns, shrubs, and mosses, too.

15  It is a forest of trees that forms seeds in cones.  The main type of trees are conifers.  Trees are shaped like triangles so that snow falls off.  Their leaves are shaped like needles and they stay green all year round..  For that they are called evergreen trees.  There are many lakes and streams which provide habitat to squirrels, moose, and wolves. There are some insects, too.

16  An ecosystem is all the living and non-living things that interact together in a specific environment.


18  Examples of a population are:  - a group of swans in a pond,  - a school of fish in a river,  - and a herd of cattle in the grassland.

19  A community is all the populations that live together in an ecosystem.

20  An example of a dry-land community would be a forest made up of trees, squirrels, worms, rabbits, and hawks.

21  An example of a water-related community would be an ocean made up of fish, crabs, and seaweed.

22  Organisms compete for the limited resources in their specific environment.  Humans need to help conserve limited resources.  Can you list ways that humans can help conserve limited resources?

23  We can:  stop over harvesting species, such as elephants, rhinos, and tigers, leopards and other big cats;  stop destroying habitats;  stop polluting and otherwise disturbing habitats; and  stop spreading non-native species(plants that originate elsewhere and are brought into a new area) Ice Plant (Carpobrotus edulis) is an extremely invasive species from South Africa.
