Question Answer
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.
