The place where an animal or plant lives and grows: a home. Everything around a plant or animal is its habitat.
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.
It is water that has very little salt in it. Lakes, rivers, ponds, and some marshes are freshwater ecosystems. We drink fresh water.
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.
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).
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.
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.
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.
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.
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.
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.
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.
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.
An ecosystem is all the living and non-living things that interact together in a specific environment.
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.
A community is all the populations that live together in an ecosystem.
An example of a dry-land community would be a forest made up of trees, squirrels, worms, rabbits, and hawks.
An example of a water-related community would be an ocean made up of fish, crabs, and seaweed.
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?
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.
