| the living or once-living parts of an environment | Biotic
🗑
|
||||
| the non-living parts that the living parts of an environment need to survive. | Abiotic
🗑
|
||||
| is a geographic area on Earth that contains ecosystems with similar biotic and abiotic features. | Biome
🗑
|
||||
| are biomes that receive very little rain. Earth's driest ecosystems. Most are hot during the day and cold at night and some remain cold all the time. Animals: lizards, snakes Plants: cactus, thorny shrubs | DESERT
🗑
|
||||
| biomes are areas where grasses are the dominant plants. Also called prairies, savanna and meadows. They have wet and dry seasons, deep fertile soil. Animals: hawks, wolves, prairie dogs Plants: grasses | GRASSLAND
🗑
|
||||
| forests that grow near the equator. They receive large amounts of rain, weather is warm and wet year round. *Half of Earth's species live in the tropical rain forest especially in the canopy of trees. | TROPICAL RAIN FOREST
🗑
|
||||
| region of Earth between the tropics and the polar circles. They have mild climates with distinct seasons. Soil is rich and moist. Animals: mosquitoes, wookpeckers, owls, deer, elk Plants: spruces, cedar, firs, redwood | TEMPERATE DECIDUOUS FOREST
🗑
|
||||
| is a forest biome consisting mostly of cone-bearing evergreen trees. It occupies more space on Earth's continents than any other biome. Winter are long,summers are short, and the soil is thin and acidic. Animals: owls, mice, moose, bears | TAIGA
🗑
|
||||
| is cold, dry and treeless. Winters are long and freezing and soil remains permanently frozen (permafrost) which prevents deep root growth. Animals: polar bears Plants: mosses,lichens | TUNDRA
🗑
|
||||
| 4 major types of water, or aquatic ecosystems | 1 freshwater 2 wetland 3 estuary 4 ocean
🗑
|
||||
| is the amount of salt dissolved in water. Water in saltwater ecosystems have high salinity compared to water in freshwater ecosystems. | Salinity
🗑
|
||||
| streams, rivers, ponds and lakes. Streams form from underground sources of water. Rivers form when streams flow together. | FRESHWATER: STREAMS AND RIVERS
🗑
|
||||
| are aquatic ecosystems that have a thin layer of water covering soil that is wet most of the time. Wetlands contain freshwater, salt water, or both. They are among Earth's most fertile ecosystems. . | WETLANDS
🗑
|
||||
| are regions along coastlines where streams or rivers flow into a body of salt water. Have varying degrees of salinity. | ESTUARIES
🗑
|
||||
| Most of Earth's surface is covered by ocean water with high salinity. | OCEANS
🗑
|
||||
| is the ocean shore between the lowest low tide and the highest high tide. | Intertidal Zone:
🗑
|
||||
| is an underwater structure made from outside skeletons of tiny, soft bodied animals called coral | Coral Reef:
🗑
|
||||
| Ecological Succession | the process of one ecological community gradually changing
into another.
🗑
|
||||
| Climax community | a stable community that no longer goes through major ecological
changes.
🗑
|
||||
| Pioneer species | the first species that colonize new or undisturbed land.
🗑
|
||||
| Aquatic succession: | when a freshwater ecosystem changes over time in a natural,
predictable process.
🗑
|
||||
| Eutrophication | the process of a body of water becoming nutrient-rich. This is a
natural part of aquatic succession.
🗑
